Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506496, here are decompositions:

17 + 31506479 = 31506496
53 + 31506443 = 31506496
59 + 31506437 = 31506496
137 + 31506359 = 31506496
233 + 31506263 = 31506496
347 + 31506149 = 31506496
467 + 31506029 = 31506496
503 + 31505993 = 31506496

Showing the first eight; more decompositions exist.
