Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461684, here are decompositions:

11 + 31461673 = 31461684
31 + 31461653 = 31461684
43 + 31461641 = 31461684
113 + 31461571 = 31461684
127 + 31461557 = 31461684
131 + 31461553 = 31461684
151 + 31461533 = 31461684
167 + 31461517 = 31461684

Showing the first eight; more decompositions exist.
