Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465790, here are decompositions:

43 + 31465747 = 31465790
79 + 31465711 = 31465790
127 + 31465663 = 31465790
211 + 31465579 = 31465790
229 + 31465561 = 31465790
331 + 31465459 = 31465790
373 + 31465417 = 31465790
547 + 31465243 = 31465790

Showing the first eight; more decompositions exist.
