Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496426, here are decompositions:

7 + 31496419 = 31496426
37 + 31496389 = 31496426
97 + 31496329 = 31496426
109 + 31496317 = 31496426
163 + 31496263 = 31496426
307 + 31496119 = 31496426
547 + 31495879 = 31496426
607 + 31495819 = 31496426

Showing the first eight; more decompositions exist.
