Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461624, here are decompositions:

53 + 31461571 = 31461624
67 + 31461557 = 31461624
71 + 31461553 = 31461624
101 + 31461523 = 31461624
107 + 31461517 = 31461624
137 + 31461487 = 31461624
167 + 31461457 = 31461624
197 + 31461427 = 31461624

Showing the first eight; more decompositions exist.
