Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540802, here are decompositions:

19 + 31540783 = 31540802
79 + 31540723 = 31540802
103 + 31540699 = 31540802
109 + 31540693 = 31540802
151 + 31540651 = 31540802
229 + 31540573 = 31540802
313 + 31540489 = 31540802
331 + 31540471 = 31540802

Showing the first eight; more decompositions exist.
