Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495814, here are decompositions:

13 + 31495801 = 31495814
61 + 31495753 = 31495814
73 + 31495741 = 31495814
151 + 31495663 = 31495814
157 + 31495657 = 31495814
211 + 31495603 = 31495814
223 + 31495591 = 31495814
313 + 31495501 = 31495814

Showing the first eight; more decompositions exist.
