Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485464, here are decompositions:

37 + 31485427 = 31485464
67 + 31485397 = 31485464
151 + 31485313 = 31485464
163 + 31485301 = 31485464
181 + 31485283 = 31485464
271 + 31485193 = 31485464
397 + 31485067 = 31485464
433 + 31485031 = 31485464

Showing the first eight; more decompositions exist.
