Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553082, here are decompositions:

5 + 31553077 = 31553082
13 + 31553069 = 31553082
19 + 31553063 = 31553082
61 + 31553021 = 31553082
83 + 31552999 = 31553082
139 + 31552943 = 31553082
163 + 31552919 = 31553082
191 + 31552891 = 31553082

Showing the first eight; more decompositions exist.
