Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553302, here are decompositions:

23 + 31553279 = 31553302
29 + 31553273 = 31553302
41 + 31553261 = 31553302
83 + 31553219 = 31553302
89 + 31553213 = 31553302
101 + 31553201 = 31553302
233 + 31553069 = 31553302
239 + 31553063 = 31553302

Showing the first eight; more decompositions exist.
