Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610742, here are decompositions:

13 + 31610729 = 31610742
19 + 31610723 = 31610742
101 + 31610641 = 31610742
103 + 31610639 = 31610742
113 + 31610629 = 31610742
173 + 31610569 = 31610742
179 + 31610563 = 31610742
181 + 31610561 = 31610742

Showing the first eight; more decompositions exist.
