Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496438, here are decompositions:

19 + 31496419 = 31496438
67 + 31496371 = 31496438
109 + 31496329 = 31496438
229 + 31496209 = 31496438
277 + 31496161 = 31496438
397 + 31496041 = 31496438
541 + 31495897 = 31496438
619 + 31495819 = 31496438

Showing the first eight; more decompositions exist.
