Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448702, here are decompositions:

3 + 31448699 = 31448702
151 + 31448551 = 31448702
223 + 31448479 = 31448702
379 + 31448323 = 31448702
409 + 31448293 = 31448702
421 + 31448281 = 31448702
541 + 31448161 = 31448702
631 + 31448071 = 31448702

Showing the first eight; more decompositions exist.
