Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534630, here are decompositions:

41 + 31534589 = 31534630
137 + 31534493 = 31534630
173 + 31534457 = 31534630
359 + 31534271 = 31534630
383 + 31534247 = 31534630
389 + 31534241 = 31534630
431 + 31534199 = 31534630
443 + 31534187 = 31534630

Showing the first eight; more decompositions exist.
