Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448050, here are decompositions:

17 + 31448033 = 31448050
83 + 31447967 = 31448050
89 + 31447961 = 31448050
149 + 31447901 = 31448050
197 + 31447853 = 31448050
239 + 31447811 = 31448050
251 + 31447799 = 31448050
281 + 31447769 = 31448050

Showing the first eight; more decompositions exist.
