Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489514, here are decompositions:

97 + 31489417 = 31489514
103 + 31489411 = 31489514
151 + 31489363 = 31489514
271 + 31489243 = 31489514
337 + 31489177 = 31489514
367 + 31489147 = 31489514
487 + 31489027 = 31489514
523 + 31488991 = 31489514

Showing the first eight; more decompositions exist.
