Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523710, here are decompositions:

3 + 31523707 = 31523710
41 + 31523669 = 31523710
59 + 31523651 = 31523710
131 + 31523579 = 31523710
173 + 31523537 = 31523710
233 + 31523477 = 31523710
269 + 31523441 = 31523710
311 + 31523399 = 31523710

Showing the first eight; more decompositions exist.
