Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495624, here are decompositions:

23 + 31495601 = 31495624
101 + 31495523 = 31495624
107 + 31495517 = 31495624
113 + 31495511 = 31495624
131 + 31495493 = 31495624
257 + 31495367 = 31495624
263 + 31495361 = 31495624
383 + 31495241 = 31495624

Showing the first eight; more decompositions exist.
