Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452046, here are decompositions:

5 + 31452041 = 31452046
47 + 31451999 = 31452046
53 + 31451993 = 31452046
137 + 31451909 = 31452046
239 + 31451807 = 31452046
293 + 31451753 = 31452046
317 + 31451729 = 31452046
347 + 31451699 = 31452046

Showing the first eight; more decompositions exist.
