Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461536, here are decompositions:

3 + 31461533 = 31461536
13 + 31461523 = 31461536
19 + 31461517 = 31461536
79 + 31461457 = 31461536
109 + 31461427 = 31461536
193 + 31461343 = 31461536
283 + 31461253 = 31461536
307 + 31461229 = 31461536

Showing the first eight; more decompositions exist.
