Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537592, here are decompositions:

19 + 31537573 = 31537592
283 + 31537309 = 31537592
349 + 31537243 = 31537592
439 + 31537153 = 31537592
601 + 31536991 = 31537592
769 + 31536823 = 31537592
859 + 31536733 = 31537592
1063 + 31536529 = 31537592

Showing the first eight; more decompositions exist.
