Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553414, here are decompositions:

31 + 31553383 = 31553414
181 + 31553233 = 31553414
337 + 31553077 = 31553414
397 + 31553017 = 31553414
523 + 31552891 = 31553414
733 + 31552681 = 31553414
811 + 31552603 = 31553414
877 + 31552537 = 31553414

Showing the first eight; more decompositions exist.
