Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495792, here are decompositions:

59 + 31495733 = 31495792
101 + 31495691 = 31495792
131 + 31495661 = 31495792
191 + 31495601 = 31495792
269 + 31495523 = 31495792
281 + 31495511 = 31495792
311 + 31495481 = 31495792
389 + 31495403 = 31495792

Showing the first eight; more decompositions exist.
