Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448010, here are decompositions:

23 + 31447987 = 31448010
43 + 31447967 = 31448010
47 + 31447963 = 31448010
53 + 31447957 = 31448010
59 + 31447951 = 31448010
79 + 31447931 = 31448010
107 + 31447903 = 31448010
109 + 31447901 = 31448010

Showing the first eight; more decompositions exist.
