Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458482, here are decompositions:

31 + 31458451 = 31458482
79 + 31458403 = 31458482
103 + 31458379 = 31458482
109 + 31458373 = 31458482
151 + 31458331 = 31458482
313 + 31458169 = 31458482
421 + 31458061 = 31458482
571 + 31457911 = 31458482

Showing the first eight; more decompositions exist.
