Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600554, here are decompositions:

5 + 31600549 = 31600554
23 + 31600531 = 31600554
31 + 31600523 = 31600554
43 + 31600511 = 31600554
61 + 31600493 = 31600554
101 + 31600453 = 31600554
103 + 31600451 = 31600554
107 + 31600447 = 31600554

Showing the first eight; more decompositions exist.
