Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448412, here are decompositions:

31 + 31448381 = 31448412
43 + 31448369 = 31448412
89 + 31448323 = 31448412
103 + 31448309 = 31448412
109 + 31448303 = 31448412
113 + 31448299 = 31448412
131 + 31448281 = 31448412
179 + 31448233 = 31448412

Showing the first eight; more decompositions exist.
