Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465862, here are decompositions:

13 + 31465849 = 31465862
31 + 31465831 = 31465862
61 + 31465801 = 31465862
73 + 31465789 = 31465862
151 + 31465711 = 31465862
199 + 31465663 = 31465862
283 + 31465579 = 31465862
499 + 31465363 = 31465862

Showing the first eight; more decompositions exist.
