Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483726, here are decompositions:

3 + 31483723 = 31483726
149 + 31483577 = 31483726
173 + 31483553 = 31483726
179 + 31483547 = 31483726
233 + 31483493 = 31483726
257 + 31483469 = 31483726
269 + 31483457 = 31483726
293 + 31483433 = 31483726

Showing the first eight; more decompositions exist.
