Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553046, here are decompositions:

29 + 31553017 = 31553046
47 + 31552999 = 31553046
103 + 31552943 = 31553046
127 + 31552919 = 31553046
139 + 31552907 = 31553046
163 + 31552883 = 31553046
167 + 31552879 = 31553046
193 + 31552853 = 31553046

Showing the first eight; more decompositions exist.
