Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599862, here are decompositions:

3 + 31599859 = 31599862
53 + 31599809 = 31599862
89 + 31599773 = 31599862
101 + 31599761 = 31599862
179 + 31599683 = 31599862
191 + 31599671 = 31599862
233 + 31599629 = 31599862
251 + 31599611 = 31599862

Showing the first eight; more decompositions exist.
