Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610658, here are decompositions:

17 + 31610641 = 31610658
19 + 31610639 = 31610658
29 + 31610629 = 31610658
71 + 31610587 = 31610658
89 + 31610569 = 31610658
97 + 31610561 = 31610658
137 + 31610521 = 31610658
139 + 31610519 = 31610658

Showing the first eight; more decompositions exist.
