Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448332, here are decompositions:

11 + 31448321 = 31448332
23 + 31448309 = 31448332
29 + 31448303 = 31448332
131 + 31448201 = 31448332
191 + 31448141 = 31448332
263 + 31448069 = 31448332
401 + 31447931 = 31448332
431 + 31447901 = 31448332

Showing the first eight; more decompositions exist.
