Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537964, here are decompositions:

43 + 31537921 = 31537964
61 + 31537903 = 31537964
103 + 31537861 = 31537964
127 + 31537837 = 31537964
223 + 31537741 = 31537964
277 + 31537687 = 31537964
373 + 31537591 = 31537964
421 + 31537543 = 31537964

Showing the first eight; more decompositions exist.
