Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475734, here are decompositions:

53 + 31475681 = 31475734
137 + 31475597 = 31475734
263 + 31475471 = 31475734
281 + 31475453 = 31475734
347 + 31475387 = 31475734
491 + 31475243 = 31475734
503 + 31475231 = 31475734
593 + 31475141 = 31475734

Showing the first eight; more decompositions exist.
