Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988290, here are decompositions:

  • 11 + 988279 = 988290
  • 19 + 988271 = 988290
  • 47 + 988243 = 988290
  • 53 + 988237 = 988290
  • 59 + 988231 = 988290
  • 71 + 988219 = 988290
  • 73 + 988217 = 988290
  • 179 + 988111 = 988290

Showing the first eight; more decompositions exist.
