Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537622, here are decompositions:

13 + 31537609 = 31537622
19 + 31537603 = 31537622
31 + 31537591 = 31537622
79 + 31537543 = 31537622
283 + 31537339 = 31537622
313 + 31537309 = 31537622
349 + 31537273 = 31537622
379 + 31537243 = 31537622

Showing the first eight; more decompositions exist.
