Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494346, here are decompositions:

53 + 31494293 = 31494346
83 + 31494263 = 31494346
89 + 31494257 = 31494346
167 + 31494179 = 31494346
227 + 31494119 = 31494346
263 + 31494083 = 31494346
293 + 31494053 = 31494346
347 + 31493999 = 31494346

Showing the first eight; more decompositions exist.
