Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548946, here are decompositions:

89 + 31548857 = 31548946
179 + 31548767 = 31548946
197 + 31548749 = 31548946
269 + 31548677 = 31548946
293 + 31548653 = 31548946
353 + 31548593 = 31548946
383 + 31548563 = 31548946
419 + 31548527 = 31548946

Showing the first eight; more decompositions exist.
