Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655290, here are decompositions:

  • 3 + 8655287 = 8655290
  • 31 + 8655259 = 8655290
  • 73 + 8655217 = 8655290
  • 79 + 8655211 = 8655290
  • 283 + 8655007 = 8655290
  • 331 + 8654959 = 8655290
  • 349 + 8654941 = 8655290
  • 373 + 8654917 = 8655290

Showing the first eight; more decompositions exist.
