Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496198, here are decompositions:

37 + 31496161 = 31496198
79 + 31496119 = 31496198
157 + 31496041 = 31496198
277 + 31495921 = 31496198
379 + 31495819 = 31496198
397 + 31495801 = 31496198
457 + 31495741 = 31496198
541 + 31495657 = 31496198

Showing the first eight; more decompositions exist.
