Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483690, here are decompositions:

41 + 31483649 = 31483690
107 + 31483583 = 31483690
113 + 31483577 = 31483690
137 + 31483553 = 31483690
197 + 31483493 = 31483690
233 + 31483457 = 31483690
257 + 31483433 = 31483690
383 + 31483307 = 31483690

Showing the first eight; more decompositions exist.
