Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552552, here are decompositions:

  • 131 + 31552421 = 31552552
  • 149 + 31552403 = 31552552
  • 281 + 31552271 = 31552552
  • 359 + 31552193 = 31552552
  • 503 + 31552049 = 31552552
  • 593 + 31551959 = 31552552
  • 881 + 31551671 = 31552552
  • 953 + 31551599 = 31552552

Showing the first eight; more decompositions exist.
