Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429494, here are decompositions:

  • 53 + 2147429441 = 2147429494
  • 131 + 2147429363 = 2147429494
  • 257 + 2147429237 = 2147429494
  • 281 + 2147429213 = 2147429494
  • 311 + 2147429183 = 2147429494
  • 347 + 2147429147 = 2147429494
  • 491 + 2147429003 = 2147429494
  • 503 + 2147428991 = 2147429494

Showing the first eight; more decompositions exist.
