Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554762, here are decompositions:

13 + 31554749 = 31554762
23 + 31554739 = 31554762
53 + 31554709 = 31554762
103 + 31554659 = 31554762
131 + 31554631 = 31554762
149 + 31554613 = 31554762
179 + 31554583 = 31554762
191 + 31554571 = 31554762

Showing the first eight; more decompositions exist.
