Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495204, here are decompositions:

5 + 31495199 = 31495204
17 + 31495187 = 31495204
47 + 31495157 = 31495204
281 + 31494923 = 31495204
317 + 31494887 = 31495204
467 + 31494737 = 31495204
491 + 31494713 = 31495204
593 + 31494611 = 31495204

Showing the first eight; more decompositions exist.
