Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600632, here are decompositions:

13 + 31600619 = 31600632
83 + 31600549 = 31600632
101 + 31600531 = 31600632
103 + 31600529 = 31600632
109 + 31600523 = 31600632
139 + 31600493 = 31600632
179 + 31600453 = 31600632
181 + 31600451 = 31600632

Showing the first eight; more decompositions exist.
