Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495434, here are decompositions:

11 + 31495423 = 31495434
17 + 31495417 = 31495434
31 + 31495403 = 31495434
67 + 31495367 = 31495434
73 + 31495361 = 31495434
83 + 31495351 = 31495434
101 + 31495333 = 31495434
193 + 31495241 = 31495434

Showing the first eight; more decompositions exist.
