Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506914, here are decompositions:

3 + 31506911 = 31506914
7 + 31506907 = 31506914
73 + 31506841 = 31506914
337 + 31506577 = 31506914
541 + 31506373 = 31506914
547 + 31506367 = 31506914
631 + 31506283 = 31506914
643 + 31506271 = 31506914

Showing the first eight; more decompositions exist.
