Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547758, here are decompositions:

149 + 31547609 = 31547758
167 + 31547591 = 31547758
227 + 31547531 = 31547758
239 + 31547519 = 31547758
251 + 31547507 = 31547758
269 + 31547489 = 31547758
317 + 31547441 = 31547758
401 + 31547357 = 31547758

Showing the first eight; more decompositions exist.
