Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616624, here are decompositions:

103 + 31616521 = 31616624
223 + 31616401 = 31616624
337 + 31616287 = 31616624
367 + 31616257 = 31616624
373 + 31616251 = 31616624
577 + 31616047 = 31616624
601 + 31616023 = 31616624
607 + 31616017 = 31616624

Showing the first eight; more decompositions exist.
