Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495602, here are decompositions:

11 + 31495591 = 31495602
13 + 31495589 = 31495602
79 + 31495523 = 31495602
101 + 31495501 = 31495602
109 + 31495493 = 31495602
139 + 31495463 = 31495602
179 + 31495423 = 31495602
199 + 31495403 = 31495602

Showing the first eight; more decompositions exist.
