Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461488, here are decompositions:

7 + 31461481 = 31461488
31 + 31461457 = 31461488
61 + 31461427 = 31461488
127 + 31461361 = 31461488
139 + 31461349 = 31461488
307 + 31461181 = 31461488
439 + 31461049 = 31461488
571 + 31460917 = 31461488

Showing the first eight; more decompositions exist.
