Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506592, here are decompositions:

23 + 31506569 = 31506592
71 + 31506521 = 31506592
113 + 31506479 = 31506592
149 + 31506443 = 31506592
233 + 31506359 = 31506592
239 + 31506353 = 31506592
281 + 31506311 = 31506592
419 + 31506173 = 31506592

Showing the first eight; more decompositions exist.
