Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495754, here are decompositions:

13 + 31495741 = 31495754
61 + 31495693 = 31495754
97 + 31495657 = 31495754
151 + 31495603 = 31495754
163 + 31495591 = 31495754
307 + 31495447 = 31495754
331 + 31495423 = 31495754
337 + 31495417 = 31495754

Showing the first eight; more decompositions exist.
