Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448934, here are decompositions:

31 + 31448903 = 31448934
37 + 31448897 = 31448934
43 + 31448891 = 31448934
71 + 31448863 = 31448934
113 + 31448821 = 31448934
131 + 31448803 = 31448934
193 + 31448741 = 31448934
227 + 31448707 = 31448934

Showing the first eight; more decompositions exist.
