Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610762, here are decompositions:

181 + 31610581 = 31610762
193 + 31610569 = 31610762
199 + 31610563 = 31610762
223 + 31610539 = 31610762
241 + 31610521 = 31610762
349 + 31610413 = 31610762
373 + 31610389 = 31610762
409 + 31610353 = 31610762

Showing the first eight; more decompositions exist.
