Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448416, here are decompositions:

3 + 31448413 = 31448416
47 + 31448369 = 31448416
107 + 31448309 = 31448416
113 + 31448303 = 31448416
347 + 31448069 = 31448416
359 + 31448057 = 31448416
383 + 31448033 = 31448416
449 + 31447967 = 31448416

Showing the first eight; more decompositions exist.
