Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495976, here are decompositions:

79 + 31495897 = 31495976
97 + 31495879 = 31495976
157 + 31495819 = 31495976
223 + 31495753 = 31495976
283 + 31495693 = 31495976
313 + 31495663 = 31495976
373 + 31495603 = 31495976
619 + 31495357 = 31495976

Showing the first eight; more decompositions exist.
