Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495346, here are decompositions:

13 + 31495333 = 31495346
73 + 31495273 = 31495346
193 + 31495153 = 31495346
199 + 31495147 = 31495346
229 + 31495117 = 31495346
283 + 31495063 = 31495346
367 + 31494979 = 31495346
397 + 31494949 = 31495346

Showing the first eight; more decompositions exist.
