Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495612, here are decompositions:

11 + 31495601 = 31495612
23 + 31495589 = 31495612
89 + 31495523 = 31495612
101 + 31495511 = 31495612
131 + 31495481 = 31495612
149 + 31495463 = 31495612
251 + 31495361 = 31495612
503 + 31495109 = 31495612

Showing the first eight; more decompositions exist.
