Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447492, here are decompositions:

5 + 31447487 = 31447492
53 + 31447439 = 31447492
113 + 31447379 = 31447492
191 + 31447301 = 31447492
239 + 31447253 = 31447492
281 + 31447211 = 31447492
311 + 31447181 = 31447492
359 + 31447133 = 31447492

Showing the first eight; more decompositions exist.
