Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540760, here are decompositions:

37 + 31540723 = 31540760
61 + 31540699 = 31540760
67 + 31540693 = 31540760
103 + 31540657 = 31540760
109 + 31540651 = 31540760
271 + 31540489 = 31540760
397 + 31540363 = 31540760
421 + 31540339 = 31540760

Showing the first eight; more decompositions exist.
