Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516060, here are decompositions:

53 + 31516007 = 31516060
71 + 31515989 = 31516060
167 + 31515893 = 31516060
179 + 31515881 = 31516060
239 + 31515821 = 31516060
293 + 31515767 = 31516060
383 + 31515677 = 31516060
419 + 31515641 = 31516060

Showing the first eight; more decompositions exist.
