Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610736, here are decompositions:

7 + 31610729 = 31610736
13 + 31610723 = 31610736
29 + 31610707 = 31610736
97 + 31610639 = 31610736
107 + 31610629 = 31610736
149 + 31610587 = 31610736
163 + 31610573 = 31610736
167 + 31610569 = 31610736

Showing the first eight; more decompositions exist.
