Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616672, here are decompositions:

103 + 31616569 = 31616672
151 + 31616521 = 31616672
163 + 31616509 = 31616672
193 + 31616479 = 31616672
271 + 31616401 = 31616672
313 + 31616359 = 31616672
421 + 31616251 = 31616672
499 + 31616173 = 31616672

Showing the first eight; more decompositions exist.
