Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577126, here are decompositions:

13 + 31577113 = 31577126
43 + 31577083 = 31577126
73 + 31577053 = 31577126
109 + 31577017 = 31577126
283 + 31576843 = 31577126
349 + 31576777 = 31577126
367 + 31576759 = 31577126
487 + 31576639 = 31577126

Showing the first eight; more decompositions exist.
