Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496138, here are decompositions:

19 + 31496119 = 31496138
97 + 31496041 = 31496138
127 + 31496011 = 31496138
241 + 31495897 = 31496138
337 + 31495801 = 31496138
397 + 31495741 = 31496138
409 + 31495729 = 31496138
547 + 31495591 = 31496138

Showing the first eight; more decompositions exist.
