Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483650, here are decompositions:

53 + 31483597 = 31483650
67 + 31483583 = 31483650
73 + 31483577 = 31483650
97 + 31483553 = 31483650
101 + 31483549 = 31483650
103 + 31483547 = 31483650
157 + 31483493 = 31483650
179 + 31483471 = 31483650

Showing the first eight; more decompositions exist.
