Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599910, here are decompositions:

101 + 31599809 = 31599910
137 + 31599773 = 31599910
149 + 31599761 = 31599910
227 + 31599683 = 31599910
239 + 31599671 = 31599910
257 + 31599653 = 31599910
281 + 31599629 = 31599910
311 + 31599599 = 31599910

Showing the first eight; more decompositions exist.
