Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498346, here are decompositions:

3 + 31498343 = 31498346
67 + 31498279 = 31498346
73 + 31498273 = 31498346
157 + 31498189 = 31498346
223 + 31498123 = 31498346
277 + 31498069 = 31498346
307 + 31498039 = 31498346
337 + 31498009 = 31498346

Showing the first eight; more decompositions exist.
