Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489596, here are decompositions:

107 + 31489489 = 31489596
163 + 31489433 = 31489596
179 + 31489417 = 31489596
197 + 31489399 = 31489596
233 + 31489363 = 31489596
317 + 31489279 = 31489596
337 + 31489259 = 31489596
349 + 31489247 = 31489596

Showing the first eight; more decompositions exist.
