Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495506, here are decompositions:

5 + 31495501 = 31495506
13 + 31495493 = 31495506
37 + 31495469 = 31495506
43 + 31495463 = 31495506
59 + 31495447 = 31495506
83 + 31495423 = 31495506
89 + 31495417 = 31495506
103 + 31495403 = 31495506

Showing the first eight; more decompositions exist.
