Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616610, here are decompositions:

7 + 31616603 = 31616610
31 + 31616579 = 31616610
41 + 31616569 = 31616610
71 + 31616539 = 31616610
89 + 31616521 = 31616610
101 + 31616509 = 31616610
131 + 31616479 = 31616610
191 + 31616419 = 31616610

Showing the first eight; more decompositions exist.
