Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449194, here are decompositions:

3 + 31449191 = 31449194
31 + 31449163 = 31449194
67 + 31449127 = 31449194
151 + 31449043 = 31449194
157 + 31449037 = 31449194
331 + 31448863 = 31449194
373 + 31448821 = 31449194
487 + 31448707 = 31449194

Showing the first eight; more decompositions exist.
