Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577096, here are decompositions:

13 + 31577083 = 31577096
43 + 31577053 = 31577096
79 + 31577017 = 31577096
139 + 31576957 = 31577096
337 + 31576759 = 31577096
457 + 31576639 = 31577096
547 + 31576549 = 31577096
613 + 31576483 = 31577096

Showing the first eight; more decompositions exist.
