Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494234, here are decompositions:

73 + 31494161 = 31494234
137 + 31494097 = 31494234
151 + 31494083 = 31494234
181 + 31494053 = 31494234
193 + 31494041 = 31494234
251 + 31493983 = 31494234
283 + 31493951 = 31494234
293 + 31493941 = 31494234

Showing the first eight; more decompositions exist.
