Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516066, here are decompositions:

5 + 31516061 = 31516066
59 + 31516007 = 31516066
167 + 31515899 = 31516066
173 + 31515893 = 31516066
347 + 31515719 = 31516066
383 + 31515683 = 31516066
389 + 31515677 = 31516066
419 + 31515647 = 31516066

Showing the first eight; more decompositions exist.
