Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483688, here are decompositions:

139 + 31483549 = 31483688
241 + 31483447 = 31483688
337 + 31483351 = 31483688
571 + 31483117 = 31483688
601 + 31483087 = 31483688
619 + 31483069 = 31483688
829 + 31482859 = 31483688
1021 + 31482667 = 31483688

Showing the first eight; more decompositions exist.
