Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462846, here are decompositions:

53 + 31462793 = 31462846
89 + 31462757 = 31462846
197 + 31462649 = 31462846
257 + 31462589 = 31462846
263 + 31462583 = 31462846
269 + 31462577 = 31462846
293 + 31462553 = 31462846
557 + 31462289 = 31462846

Showing the first eight; more decompositions exist.
