Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599874, here are decompositions:

3 + 31599871 = 31599874
101 + 31599773 = 31599874
107 + 31599767 = 31599874
113 + 31599761 = 31599874
167 + 31599707 = 31599874
191 + 31599683 = 31599874
263 + 31599611 = 31599874
311 + 31599563 = 31599874

Showing the first eight; more decompositions exist.
