Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465796, here are decompositions:

7 + 31465789 = 31465796
337 + 31465459 = 31465796
379 + 31465417 = 31465796
433 + 31465363 = 31465796
487 + 31465309 = 31465796
613 + 31465183 = 31465796
619 + 31465177 = 31465796
643 + 31465153 = 31465796

Showing the first eight; more decompositions exist.
