Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465328, here are decompositions:

7 + 31465321 = 31465328
19 + 31465309 = 31465328
151 + 31465177 = 31465328
199 + 31465129 = 31465328
229 + 31465099 = 31465328
337 + 31464991 = 31465328
541 + 31464787 = 31465328
547 + 31464781 = 31465328

Showing the first eight; more decompositions exist.
