Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616750, here are decompositions:

3 + 31616747 = 31616750
43 + 31616707 = 31616750
73 + 31616677 = 31616750
79 + 31616671 = 31616750
103 + 31616647 = 31616750
127 + 31616623 = 31616750
181 + 31616569 = 31616750
211 + 31616539 = 31616750

Showing the first eight; more decompositions exist.
