Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599766, here are decompositions:

5 + 31599761 = 31599766
59 + 31599707 = 31599766
83 + 31599683 = 31599766
113 + 31599653 = 31599766
137 + 31599629 = 31599766
167 + 31599599 = 31599766
593 + 31599173 = 31599766
827 + 31598939 = 31599766

Showing the first eight; more decompositions exist.
