Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483732, here are decompositions:

41 + 31483691 = 31483732
83 + 31483649 = 31483732
149 + 31483583 = 31483732
179 + 31483553 = 31483732
239 + 31483493 = 31483732
263 + 31483469 = 31483732
419 + 31483313 = 31483732
503 + 31483229 = 31483732

Showing the first eight; more decompositions exist.
