Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496196, here are decompositions:

23 + 31496173 = 31496196
73 + 31496123 = 31496196
97 + 31496099 = 31496196
113 + 31496083 = 31496196
139 + 31496057 = 31496196
317 + 31495879 = 31496196
337 + 31495859 = 31496196
349 + 31495847 = 31496196

Showing the first eight; more decompositions exist.
