Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516594, here are decompositions:

23 + 31516571 = 31516594
71 + 31516523 = 31516594
101 + 31516493 = 31516594
167 + 31516427 = 31516594
233 + 31516361 = 31516594
353 + 31516241 = 31516594
491 + 31516103 = 31516594
587 + 31516007 = 31516594

Showing the first eight; more decompositions exist.
