Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553514, here are decompositions:

11 + 31553503 = 31553514
61 + 31553453 = 31553514
127 + 31553387 = 31553514
131 + 31553383 = 31553514
163 + 31553351 = 31553514
193 + 31553321 = 31553514
241 + 31553273 = 31553514
281 + 31553233 = 31553514

Showing the first eight; more decompositions exist.
