Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599994, here are decompositions:

17 + 31599977 = 31599994
53 + 31599941 = 31599994
227 + 31599767 = 31599994
233 + 31599761 = 31599994
311 + 31599683 = 31599994
383 + 31599611 = 31599994
431 + 31599563 = 31599994
443 + 31599551 = 31599994

Showing the first eight; more decompositions exist.
