Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616826, here are decompositions:

53 + 31616773 = 31616826
79 + 31616747 = 31616826
97 + 31616729 = 31616826
139 + 31616687 = 31616826
149 + 31616677 = 31616826
179 + 31616647 = 31616826
223 + 31616603 = 31616826
257 + 31616569 = 31616826

Showing the first eight; more decompositions exist.
