Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553862, here are decompositions:

29 + 31553833 = 31553862
59 + 31553803 = 31553862
61 + 31553801 = 31553862
79 + 31553783 = 31553862
101 + 31553761 = 31553862
103 + 31553759 = 31553862
191 + 31553671 = 31553862
199 + 31553663 = 31553862

Showing the first eight; more decompositions exist.
