Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448082, here are decompositions:

11 + 31448071 = 31448082
13 + 31448069 = 31448082
59 + 31448023 = 31448082
131 + 31447951 = 31448082
151 + 31447931 = 31448082
179 + 31447903 = 31448082
181 + 31447901 = 31448082
229 + 31447853 = 31448082

Showing the first eight; more decompositions exist.
