Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495662, here are decompositions:

5 + 31495657 = 31495662
59 + 31495603 = 31495662
61 + 31495601 = 31495662
71 + 31495591 = 31495662
73 + 31495589 = 31495662
139 + 31495523 = 31495662
151 + 31495511 = 31495662
181 + 31495481 = 31495662

Showing the first eight; more decompositions exist.
