Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495654, here are decompositions:

53 + 31495601 = 31495654
131 + 31495523 = 31495654
137 + 31495517 = 31495654
173 + 31495481 = 31495654
191 + 31495463 = 31495654
251 + 31495403 = 31495654
293 + 31495361 = 31495654
467 + 31495187 = 31495654

Showing the first eight; more decompositions exist.
