Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465934, here are decompositions:

43 + 31465891 = 31465934
103 + 31465831 = 31465934
193 + 31465741 = 31465934
223 + 31465711 = 31465934
271 + 31465663 = 31465934
373 + 31465561 = 31465934
571 + 31465363 = 31465934
613 + 31465321 = 31465934

Showing the first eight; more decompositions exist.
