Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481098, here are decompositions:

41 + 31481057 = 31481098
59 + 31481039 = 31481098
149 + 31480949 = 31481098
179 + 31480919 = 31481098
197 + 31480901 = 31481098
269 + 31480829 = 31481098
449 + 31480649 = 31481098
569 + 31480529 = 31481098

Showing the first eight; more decompositions exist.
