Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599684, here are decompositions:

13 + 31599671 = 31599684
31 + 31599653 = 31599684
73 + 31599611 = 31599684
131 + 31599553 = 31599684
197 + 31599487 = 31599684
331 + 31599353 = 31599684
491 + 31599193 = 31599684
751 + 31598933 = 31599684

Showing the first eight; more decompositions exist.
