Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610570, here are decompositions:

7 + 31610563 = 31610570
31 + 31610539 = 31610570
67 + 31610503 = 31610570
157 + 31610413 = 31610570
181 + 31610389 = 31610570
283 + 31610287 = 31610570
373 + 31610197 = 31610570
457 + 31610113 = 31610570

Showing the first eight; more decompositions exist.
