Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638102, here are decompositions:

  • 41 + 8638061 = 8638102
  • 59 + 8638043 = 8638102
  • 149 + 8637953 = 8638102
  • 173 + 8637929 = 8638102
  • 233 + 8637869 = 8638102
  • 281 + 8637821 = 8638102
  • 311 + 8637791 = 8638102
  • 353 + 8637749 = 8638102

Showing the first eight; more decompositions exist.
