Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489504, here are decompositions:

41 + 31489463 = 31489504
71 + 31489433 = 31489504
113 + 31489391 = 31489504
257 + 31489247 = 31489504
311 + 31489193 = 31489504
461 + 31489043 = 31489504
467 + 31489037 = 31489504
587 + 31488917 = 31489504

Showing the first eight; more decompositions exist.
