Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730442, here are decompositions:

  • 89 + 8730353 = 8730442
  • 101 + 8730341 = 8730442
  • 131 + 8730311 = 8730442
  • 173 + 8730269 = 8730442
  • 179 + 8730263 = 8730442
  • 293 + 8730149 = 8730442
  • 359 + 8730083 = 8730442
  • 443 + 8729999 = 8730442

Showing the first eight; more decompositions exist.
