Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483590, here are decompositions:

7 + 31483583 = 31483590
13 + 31483577 = 31483590
37 + 31483553 = 31483590
41 + 31483549 = 31483590
43 + 31483547 = 31483590
97 + 31483493 = 31483590
137 + 31483453 = 31483590
157 + 31483433 = 31483590

Showing the first eight; more decompositions exist.
