Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485148, here are decompositions:

  • 7 + 2147485141 = 2147485148
  • 157 + 2147484991 = 2147485148
  • 199 + 2147484949 = 2147485148
  • 229 + 2147484919 = 2147485148
  • 271 + 2147484877 = 2147485148
  • 397 + 2147484751 = 2147485148
  • 547 + 2147484601 = 2147485148
  • 607 + 2147484541 = 2147485148

Showing the first eight; more decompositions exist.
