Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542482, here are decompositions:

3 + 31542479 = 31542482
43 + 31542439 = 31542482
109 + 31542373 = 31542482
379 + 31542103 = 31542482
613 + 31541869 = 31542482
823 + 31541659 = 31542482
919 + 31541563 = 31542482
1033 + 31541449 = 31542482

Showing the first eight; more decompositions exist.
