Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553222, here are decompositions:

3 + 31553219 = 31553222
61 + 31553161 = 31553222
223 + 31552999 = 31553222
331 + 31552891 = 31553222
541 + 31552681 = 31553222
601 + 31552621 = 31553222
619 + 31552603 = 31553222
643 + 31552579 = 31553222

Showing the first eight; more decompositions exist.
