Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448532, here are decompositions:

13 + 31448519 = 31448532
53 + 31448479 = 31448532
83 + 31448449 = 31448532
109 + 31448423 = 31448532
151 + 31448381 = 31448532
163 + 31448369 = 31448532
211 + 31448321 = 31448532
223 + 31448309 = 31448532

Showing the first eight; more decompositions exist.
