Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537442, here are decompositions:

103 + 31537339 = 31537442
199 + 31537243 = 31537442
241 + 31537201 = 31537442
439 + 31537003 = 31537442
499 + 31536943 = 31537442
571 + 31536871 = 31537442
613 + 31536829 = 31537442
619 + 31536823 = 31537442

Showing the first eight; more decompositions exist.
