Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550936, here are decompositions:

13 + 31550923 = 31550936
103 + 31550833 = 31550936
139 + 31550797 = 31550936
337 + 31550599 = 31550936
349 + 31550587 = 31550936
367 + 31550569 = 31550936
379 + 31550557 = 31550936
397 + 31550539 = 31550936

Showing the first eight; more decompositions exist.
