Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448292, here are decompositions:

11 + 31448281 = 31448292
59 + 31448233 = 31448292
101 + 31448191 = 31448292
131 + 31448161 = 31448292
151 + 31448141 = 31448292
181 + 31448111 = 31448292
223 + 31448069 = 31448292
269 + 31448023 = 31448292

Showing the first eight; more decompositions exist.
