Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496258, here are decompositions:

37 + 31496221 = 31496258
97 + 31496161 = 31496258
139 + 31496119 = 31496258
337 + 31495921 = 31496258
379 + 31495879 = 31496258
439 + 31495819 = 31496258
457 + 31495801 = 31496258
601 + 31495657 = 31496258

Showing the first eight; more decompositions exist.
