Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495614, here are decompositions:

11 + 31495603 = 31495614
13 + 31495601 = 31495614
23 + 31495591 = 31495614
97 + 31495517 = 31495614
103 + 31495511 = 31495614
113 + 31495501 = 31495614
151 + 31495463 = 31495614
167 + 31495447 = 31495614

Showing the first eight; more decompositions exist.
