Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499604, here are decompositions:

5 + 31499599 = 31499604
11 + 31499593 = 31499604
43 + 31499561 = 31499604
67 + 31499537 = 31499604
107 + 31499497 = 31499604
113 + 31499491 = 31499604
137 + 31499467 = 31499604
173 + 31499431 = 31499604

Showing the first eight; more decompositions exist.
