Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599986, here are decompositions:

73 + 31599913 = 31599986
109 + 31599877 = 31599986
127 + 31599859 = 31599986
163 + 31599823 = 31599986
283 + 31599703 = 31599986
337 + 31599649 = 31599986
433 + 31599553 = 31599986
487 + 31599499 = 31599986

Showing the first eight; more decompositions exist.
