Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448876, here are decompositions:

13 + 31448863 = 31448876
37 + 31448839 = 31448876
73 + 31448803 = 31448876
157 + 31448719 = 31448876
163 + 31448713 = 31448876
229 + 31448647 = 31448876
397 + 31448479 = 31448876
463 + 31448413 = 31448876

Showing the first eight; more decompositions exist.
