Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481050, here are decompositions:

11 + 31481039 = 31481050
101 + 31480949 = 31481050
131 + 31480919 = 31481050
137 + 31480913 = 31481050
149 + 31480901 = 31481050
257 + 31480793 = 31481050
281 + 31480769 = 31481050
317 + 31480733 = 31481050

Showing the first eight; more decompositions exist.
