Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616862, here are decompositions:

5 + 31616857 = 31616862
23 + 31616839 = 31616862
89 + 31616773 = 31616862
113 + 31616749 = 31616862
191 + 31616671 = 31616862
239 + 31616623 = 31616862
283 + 31616579 = 31616862
293 + 31616569 = 31616862

Showing the first eight; more decompositions exist.
