Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610588, here are decompositions:

7 + 31610581 = 31610588
19 + 31610569 = 31610588
67 + 31610521 = 31610588
151 + 31610437 = 31610588
199 + 31610389 = 31610588
271 + 31610317 = 31610588
577 + 31610011 = 31610588
631 + 31609957 = 31610588

Showing the first eight; more decompositions exist.
