Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461796, here are decompositions:

5 + 31461791 = 31461796
17 + 31461779 = 31461796
53 + 31461743 = 31461796
59 + 31461737 = 31461796
227 + 31461569 = 31461796
239 + 31461557 = 31461796
263 + 31461533 = 31461796
383 + 31461413 = 31461796

Showing the first eight; more decompositions exist.
