Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616648, here are decompositions:

79 + 31616569 = 31616648
109 + 31616539 = 31616648
127 + 31616521 = 31616648
139 + 31616509 = 31616648
229 + 31616419 = 31616648
367 + 31616281 = 31616648
397 + 31616251 = 31616648
499 + 31616149 = 31616648

Showing the first eight; more decompositions exist.
