Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540844, here are decompositions:

7 + 31540837 = 31540844
31 + 31540813 = 31540844
61 + 31540783 = 31540844
151 + 31540693 = 31540844
193 + 31540651 = 31540844
271 + 31540573 = 31540844
373 + 31540471 = 31540844
547 + 31540297 = 31540844

Showing the first eight; more decompositions exist.
