Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599838, here are decompositions:

29 + 31599809 = 31599838
71 + 31599767 = 31599838
131 + 31599707 = 31599838
167 + 31599671 = 31599838
227 + 31599611 = 31599838
239 + 31599599 = 31599838
449 + 31599389 = 31599838
911 + 31598927 = 31599838

Showing the first eight; more decompositions exist.
