Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494394, here are decompositions:

5 + 31494389 = 31494394
47 + 31494347 = 31494394
101 + 31494293 = 31494394
131 + 31494263 = 31494394
137 + 31494257 = 31494394
233 + 31494161 = 31494394
251 + 31494143 = 31494394
311 + 31494083 = 31494394

Showing the first eight; more decompositions exist.
