Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448600, here are decompositions:

13 + 31448587 = 31448600
19 + 31448581 = 31448600
67 + 31448533 = 31448600
151 + 31448449 = 31448600
223 + 31448377 = 31448600
277 + 31448323 = 31448600
307 + 31448293 = 31448600
367 + 31448233 = 31448600

Showing the first eight; more decompositions exist.
