Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448814, here are decompositions:

11 + 31448803 = 31448814
73 + 31448741 = 31448814
97 + 31448717 = 31448814
101 + 31448713 = 31448814
107 + 31448707 = 31448814
167 + 31448647 = 31448814
193 + 31448621 = 31448814
211 + 31448603 = 31448814

Showing the first eight; more decompositions exist.
