Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448892, here are decompositions:

29 + 31448863 = 31448892
53 + 31448839 = 31448892
71 + 31448821 = 31448892
89 + 31448803 = 31448892
151 + 31448741 = 31448892
173 + 31448719 = 31448892
179 + 31448713 = 31448892
193 + 31448699 = 31448892

Showing the first eight; more decompositions exist.
