Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702990, here are decompositions:

  • 31 + 8702959 = 8702990
  • 151 + 8702839 = 8702990
  • 157 + 8702833 = 8702990
  • 397 + 8702593 = 8702990
  • 421 + 8702569 = 8702990
  • 433 + 8702557 = 8702990
  • 487 + 8702503 = 8702990
  • 619 + 8702371 = 8702990

Showing the first eight; more decompositions exist.
