Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546590, here are decompositions:

7 + 31546583 = 31546590
17 + 31546573 = 31546590
37 + 31546553 = 31546590
107 + 31546483 = 31546590
139 + 31546451 = 31546590
197 + 31546393 = 31546590
239 + 31546351 = 31546590
241 + 31546349 = 31546590

Showing the first eight; more decompositions exist.
