Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544660, here are decompositions:

3 + 31544657 = 31544660
73 + 31544587 = 31544660
109 + 31544551 = 31544660
127 + 31544533 = 31544660
151 + 31544509 = 31544660
313 + 31544347 = 31544660
337 + 31544323 = 31544660
349 + 31544311 = 31544660

Showing the first eight; more decompositions exist.
