Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553202, here are decompositions:

19 + 31553183 = 31553202
41 + 31553161 = 31553202
113 + 31553089 = 31553202
139 + 31553063 = 31553202
181 + 31553021 = 31553202
283 + 31552919 = 31553202
311 + 31552891 = 31553202
349 + 31552853 = 31553202

Showing the first eight; more decompositions exist.
