Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482940, here are decompositions:

101 + 31482839 = 31482940
107 + 31482833 = 31482940
179 + 31482761 = 31482940
197 + 31482743 = 31482940
233 + 31482707 = 31482940
257 + 31482683 = 31482940
353 + 31482587 = 31482940
389 + 31482551 = 31482940

Showing the first eight; more decompositions exist.
