Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616754, here are decompositions:

5 + 31616749 = 31616754
7 + 31616747 = 31616754
47 + 31616707 = 31616754
61 + 31616693 = 31616754
67 + 31616687 = 31616754
83 + 31616671 = 31616754
107 + 31616647 = 31616754
131 + 31616623 = 31616754

Showing the first eight; more decompositions exist.
