Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448898, here are decompositions:

7 + 31448891 = 31448898
59 + 31448839 = 31448898
157 + 31448741 = 31448898
179 + 31448719 = 31448898
181 + 31448717 = 31448898
191 + 31448707 = 31448898
199 + 31448699 = 31448898
251 + 31448647 = 31448898

Showing the first eight; more decompositions exist.
