Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465364, here are decompositions:

43 + 31465321 = 31465364
181 + 31465183 = 31465364
211 + 31465153 = 31465364
241 + 31465123 = 31465364
331 + 31465033 = 31465364
373 + 31464991 = 31465364
397 + 31464967 = 31465364
577 + 31464787 = 31465364

Showing the first eight; more decompositions exist.
