Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495798, here are decompositions:

41 + 31495757 = 31495798
107 + 31495691 = 31495798
137 + 31495661 = 31495798
197 + 31495601 = 31495798
281 + 31495517 = 31495798
317 + 31495481 = 31495798
431 + 31495367 = 31495798
557 + 31495241 = 31495798

Showing the first eight; more decompositions exist.
