Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537952, here are decompositions:

13 + 31537939 = 31537952
31 + 31537921 = 31537952
109 + 31537843 = 31537952
211 + 31537741 = 31537952
349 + 31537603 = 31537952
379 + 31537573 = 31537952
409 + 31537543 = 31537952
613 + 31537339 = 31537952

Showing the first eight; more decompositions exist.
