Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537976, here are decompositions:

37 + 31537939 = 31537976
73 + 31537903 = 31537976
139 + 31537837 = 31537976
229 + 31537747 = 31537976
367 + 31537609 = 31537976
373 + 31537603 = 31537976
433 + 31537543 = 31537976
499 + 31537477 = 31537976

Showing the first eight; more decompositions exist.
