Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483754, here are decompositions:

31 + 31483723 = 31483754
157 + 31483597 = 31483754
283 + 31483471 = 31483754
307 + 31483447 = 31483754
541 + 31483213 = 31483754
661 + 31483093 = 31483754
751 + 31483003 = 31483754
1087 + 31482667 = 31483754

Showing the first eight; more decompositions exist.
