Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496342, here are decompositions:

13 + 31496329 = 31496342
79 + 31496263 = 31496342
181 + 31496161 = 31496342
223 + 31496119 = 31496342
331 + 31496011 = 31496342
421 + 31495921 = 31496342
463 + 31495879 = 31496342
523 + 31495819 = 31496342

Showing the first eight; more decompositions exist.
