Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448364, here are decompositions:

41 + 31448323 = 31448364
43 + 31448321 = 31448364
61 + 31448303 = 31448364
67 + 31448297 = 31448364
71 + 31448293 = 31448364
83 + 31448281 = 31448364
131 + 31448233 = 31448364
163 + 31448201 = 31448364

Showing the first eight; more decompositions exist.
