Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448024, here are decompositions:

7 + 31448017 = 31448024
37 + 31447987 = 31448024
61 + 31447963 = 31448024
67 + 31447957 = 31448024
73 + 31447951 = 31448024
211 + 31447813 = 31448024
241 + 31447783 = 31448024
367 + 31447657 = 31448024

Showing the first eight; more decompositions exist.
