Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616564, here are decompositions:

3 + 31616561 = 31616564
43 + 31616521 = 31616564
163 + 31616401 = 31616564
277 + 31616287 = 31616564
283 + 31616281 = 31616564
307 + 31616257 = 31616564
313 + 31616251 = 31616564
523 + 31616041 = 31616564

Showing the first eight; more decompositions exist.
