Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461956, here are decompositions:

7 + 31461949 = 31461956
13 + 31461943 = 31461956
37 + 31461919 = 31461956
139 + 31461817 = 31461956
193 + 31461763 = 31461956
283 + 31461673 = 31461956
433 + 31461523 = 31461956
439 + 31461517 = 31461956

Showing the first eight; more decompositions exist.
