Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489796, here are decompositions:

43 + 31489753 = 31489796
73 + 31489723 = 31489796
277 + 31489519 = 31489796
307 + 31489489 = 31489796
379 + 31489417 = 31489796
397 + 31489399 = 31489796
433 + 31489363 = 31489796
619 + 31489177 = 31489796

Showing the first eight; more decompositions exist.
