Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495596, here are decompositions:

5 + 31495591 = 31495596
7 + 31495589 = 31495596
73 + 31495523 = 31495596
79 + 31495517 = 31495596
103 + 31495493 = 31495596
127 + 31495469 = 31495596
149 + 31495447 = 31495596
173 + 31495423 = 31495596

Showing the first eight; more decompositions exist.
