Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147453462, here are decompositions:

  • 31 + 2147453431 = 2147453462
  • 43 + 2147453419 = 2147453462
  • 61 + 2147453401 = 2147453462
  • 181 + 2147453281 = 2147453462
  • 211 + 2147453251 = 2147453462
  • 229 + 2147453233 = 2147453462
  • 463 + 2147452999 = 2147453462
  • 541 + 2147452921 = 2147453462

Showing the first eight; more decompositions exist.
