Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483292, here are decompositions:

31 + 31483261 = 31483292
79 + 31483213 = 31483292
199 + 31483093 = 31483292
223 + 31483069 = 31483292
241 + 31483051 = 31483292
433 + 31482859 = 31483292
661 + 31482631 = 31483292
733 + 31482559 = 31483292

Showing the first eight; more decompositions exist.
