Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553002, here are decompositions:

3 + 31552999 = 31553002
59 + 31552943 = 31553002
83 + 31552919 = 31553002
149 + 31552853 = 31553002
269 + 31552733 = 31553002
281 + 31552721 = 31553002
293 + 31552709 = 31553002
359 + 31552643 = 31553002

Showing the first eight; more decompositions exist.
