Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610528, here are decompositions:

7 + 31610521 = 31610528
139 + 31610389 = 31610528
211 + 31610317 = 31610528
241 + 31610287 = 31610528
331 + 31610197 = 31610528
421 + 31610107 = 31610528
571 + 31609957 = 31610528
709 + 31609819 = 31610528

Showing the first eight; more decompositions exist.
