Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610562, here are decompositions:

23 + 31610539 = 31610562
41 + 31610521 = 31610562
43 + 31610519 = 31610562
59 + 31610503 = 31610562
149 + 31610413 = 31610562
173 + 31610389 = 31610562
199 + 31610363 = 31610562
223 + 31610339 = 31610562

Showing the first eight; more decompositions exist.
