Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524930, here are decompositions:

37 + 31524893 = 31524930
67 + 31524863 = 31524930
137 + 31524793 = 31524930
139 + 31524791 = 31524930
163 + 31524767 = 31524930
167 + 31524763 = 31524930
257 + 31524673 = 31524930
389 + 31524541 = 31524930

Showing the first eight; more decompositions exist.
