Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448102, here are decompositions:

31 + 31448071 = 31448102
79 + 31448023 = 31448102
139 + 31447963 = 31448102
151 + 31447951 = 31448102
199 + 31447903 = 31448102
421 + 31447681 = 31448102
661 + 31447441 = 31448102
709 + 31447393 = 31448102

Showing the first eight; more decompositions exist.
