Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494136, here are decompositions:

17 + 31494119 = 31494136
53 + 31494083 = 31494136
83 + 31494053 = 31494136
137 + 31493999 = 31494136
227 + 31493909 = 31494136
347 + 31493789 = 31494136
353 + 31493783 = 31494136
419 + 31493717 = 31494136

Showing the first eight; more decompositions exist.
