Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553244, here are decompositions:

11 + 31553233 = 31553244
31 + 31553213 = 31553244
43 + 31553201 = 31553244
61 + 31553183 = 31553244
67 + 31553177 = 31553244
83 + 31553161 = 31553244
167 + 31553077 = 31553244
181 + 31553063 = 31553244

Showing the first eight; more decompositions exist.
