Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495834, here are decompositions:

101 + 31495733 = 31495834
173 + 31495661 = 31495834
233 + 31495601 = 31495834
311 + 31495523 = 31495834
317 + 31495517 = 31495834
353 + 31495481 = 31495834
431 + 31495403 = 31495834
467 + 31495367 = 31495834

Showing the first eight; more decompositions exist.
