Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761530, here are decompositions:

  • 13 + 8761517 = 8761530
  • 23 + 8761507 = 8761530
  • 61 + 8761469 = 8761530
  • 67 + 8761463 = 8761530
  • 73 + 8761457 = 8761530
  • 97 + 8761433 = 8761530
  • 101 + 8761429 = 8761530
  • 191 + 8761339 = 8761530

Showing the first eight; more decompositions exist.
