Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553954, here are decompositions:

151 + 31553803 = 31553954
193 + 31553761 = 31553954
283 + 31553671 = 31553954
337 + 31553617 = 31553954
571 + 31553383 = 31553954
877 + 31553077 = 31553954
937 + 31553017 = 31553954
1063 + 31552891 = 31553954

Showing the first eight; more decompositions exist.
