Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599702, here are decompositions:

19 + 31599683 = 31599702
31 + 31599671 = 31599702
53 + 31599649 = 31599702
73 + 31599629 = 31599702
103 + 31599599 = 31599702
139 + 31599563 = 31599702
149 + 31599553 = 31599702
151 + 31599551 = 31599702

Showing the first eight; more decompositions exist.
