Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384242, here are decompositions:

  • 41 + 2147384201 = 2147384242
  • 131 + 2147384111 = 2147384242
  • 239 + 2147384003 = 2147384242
  • 251 + 2147383991 = 2147384242
  • 503 + 2147383739 = 2147384242
  • 593 + 2147383649 = 2147384242
  • 761 + 2147383481 = 2147384242
  • 821 + 2147383421 = 2147384242

Showing the first eight; more decompositions exist.
