Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448302, here are decompositions:

3 + 31448299 = 31448302
5 + 31448297 = 31448302
101 + 31448201 = 31448302
131 + 31448171 = 31448302
191 + 31448111 = 31448302
233 + 31448069 = 31448302
269 + 31448033 = 31448302
401 + 31447901 = 31448302

Showing the first eight; more decompositions exist.
