Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448496, here are decompositions:

17 + 31448479 = 31448496
47 + 31448449 = 31448496
73 + 31448423 = 31448496
83 + 31448413 = 31448496
127 + 31448369 = 31448496
173 + 31448323 = 31448496
193 + 31448303 = 31448496
197 + 31448299 = 31448496

Showing the first eight; more decompositions exist.
