Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582760, here are decompositions:

3 + 31582757 = 31582760
31 + 31582729 = 31582760
127 + 31582633 = 31582760
151 + 31582609 = 31582760
229 + 31582531 = 31582760
271 + 31582489 = 31582760
439 + 31582321 = 31582760
577 + 31582183 = 31582760

Showing the first eight; more decompositions exist.
