Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660290, here are decompositions:

  • 3 + 8660287 = 8660290
  • 101 + 8660189 = 8660290
  • 113 + 8660177 = 8660290
  • 239 + 8660051 = 8660290
  • 251 + 8660039 = 8660290
  • 257 + 8660033 = 8660290
  • 293 + 8659997 = 8660290
  • 479 + 8659811 = 8660290

Showing the first eight; more decompositions exist.
