Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589444, here are decompositions:

37 + 31589407 = 31589444
43 + 31589401 = 31589444
67 + 31589377 = 31589444
127 + 31589317 = 31589444
151 + 31589293 = 31589444
157 + 31589287 = 31589444
193 + 31589251 = 31589444
277 + 31589167 = 31589444

Showing the first eight; more decompositions exist.
