Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449598, here are decompositions:

17 + 31449581 = 31449598
29 + 31449569 = 31449598
41 + 31449557 = 31449598
71 + 31449527 = 31449598
149 + 31449449 = 31449598
197 + 31449401 = 31449598
239 + 31449359 = 31449598
311 + 31449287 = 31449598

Showing the first eight; more decompositions exist.
