Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616444, here are decompositions:

43 + 31616401 = 31616444
157 + 31616287 = 31616444
163 + 31616281 = 31616444
193 + 31616251 = 31616444
271 + 31616173 = 31616444
331 + 31616113 = 31616444
397 + 31616047 = 31616444
421 + 31616023 = 31616444

Showing the first eight; more decompositions exist.
