Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553260, here are decompositions:

41 + 31553219 = 31553260
47 + 31553213 = 31553260
59 + 31553201 = 31553260
83 + 31553177 = 31553260
191 + 31553069 = 31553260
197 + 31553063 = 31553260
239 + 31553021 = 31553260
317 + 31552943 = 31553260

Showing the first eight; more decompositions exist.
