Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471316, here are decompositions:

103 + 31471213 = 31471316
109 + 31471207 = 31471316
193 + 31471123 = 31471316
223 + 31471093 = 31471316
463 + 31470853 = 31471316
523 + 31470793 = 31471316
607 + 31470709 = 31471316
769 + 31470547 = 31471316

Showing the first eight; more decompositions exist.
