Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616726, here are decompositions:

19 + 31616707 = 31616726
79 + 31616647 = 31616726
103 + 31616623 = 31616726
157 + 31616569 = 31616726
307 + 31616419 = 31616726
367 + 31616359 = 31616726
439 + 31616287 = 31616726
577 + 31616149 = 31616726

Showing the first eight; more decompositions exist.
