Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607522, here are decompositions:

19 + 31607503 = 31607522
61 + 31607461 = 31607522
73 + 31607449 = 31607522
181 + 31607341 = 31607522
223 + 31607299 = 31607522
229 + 31607293 = 31607522
241 + 31607281 = 31607522
421 + 31607101 = 31607522

Showing the first eight; more decompositions exist.
