Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475746, here are decompositions:

149 + 31475597 = 31475746
167 + 31475579 = 31475746
257 + 31475489 = 31475746
293 + 31475453 = 31475746
317 + 31475429 = 31475746
353 + 31475393 = 31475746
359 + 31475387 = 31475746
503 + 31475243 = 31475746

Showing the first eight; more decompositions exist.
