Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492796, here are decompositions:

19 + 31492777 = 31492796
193 + 31492603 = 31492796
199 + 31492597 = 31492796
229 + 31492567 = 31492796
367 + 31492429 = 31492796
373 + 31492423 = 31492796
397 + 31492399 = 31492796
883 + 31491913 = 31492796

Showing the first eight; more decompositions exist.
