Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495486, here are decompositions:

5 + 31495481 = 31495486
17 + 31495469 = 31495486
23 + 31495463 = 31495486
83 + 31495403 = 31495486
443 + 31495043 = 31495486
467 + 31495019 = 31495486
563 + 31494923 = 31495486
599 + 31494887 = 31495486

Showing the first eight; more decompositions exist.
