Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483394, here are decompositions:

3 + 31483391 = 31483394
43 + 31483351 = 31483394
67 + 31483327 = 31483394
157 + 31483237 = 31483394
181 + 31483213 = 31483394
277 + 31483117 = 31483394
307 + 31483087 = 31483394
421 + 31482973 = 31483394

Showing the first eight; more decompositions exist.
