Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731370, here are decompositions:

  • 7 + 8731363 = 8731370
  • 31 + 8731339 = 8731370
  • 61 + 8731309 = 8731370
  • 139 + 8731231 = 8731370
  • 157 + 8731213 = 8731370
  • 229 + 8731141 = 8731370
  • 331 + 8731039 = 8731370
  • 421 + 8730949 = 8731370

Showing the first eight; more decompositions exist.
