Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553308, here are decompositions:

29 + 31553279 = 31553308
47 + 31553261 = 31553308
89 + 31553219 = 31553308
107 + 31553201 = 31553308
131 + 31553177 = 31553308
239 + 31553069 = 31553308
389 + 31552919 = 31553308
401 + 31552907 = 31553308

Showing the first eight; more decompositions exist.
