Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461646, here are decompositions:

5 + 31461641 = 31461646
89 + 31461557 = 31461646
113 + 31461533 = 31461646
233 + 31461413 = 31461646
353 + 31461293 = 31461646
467 + 31461179 = 31461646
599 + 31461047 = 31461646
719 + 31460927 = 31461646

Showing the first eight; more decompositions exist.
