Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547848, here are decompositions:

11 + 31547837 = 31547848
239 + 31547609 = 31547848
257 + 31547591 = 31547848
317 + 31547531 = 31547848
359 + 31547489 = 31547848
389 + 31547459 = 31547848
491 + 31547357 = 31547848
509 + 31547339 = 31547848

Showing the first eight; more decompositions exist.
