Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496186, here are decompositions:

13 + 31496173 = 31496186
67 + 31496119 = 31496186
103 + 31496083 = 31496186
307 + 31495879 = 31496186
367 + 31495819 = 31496186
433 + 31495753 = 31496186
457 + 31495729 = 31496186
523 + 31495663 = 31496186

Showing the first eight; more decompositions exist.
