Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495446, here are decompositions:

23 + 31495423 = 31495446
29 + 31495417 = 31495446
43 + 31495403 = 31495446
79 + 31495367 = 31495446
89 + 31495357 = 31495446
113 + 31495333 = 31495446
173 + 31495273 = 31495446
233 + 31495213 = 31495446

Showing the first eight; more decompositions exist.
