Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554338, here are decompositions:

97 + 31554241 = 31554338
139 + 31554199 = 31554338
157 + 31554181 = 31554338
577 + 31553761 = 31554338
619 + 31553719 = 31554338
631 + 31553707 = 31554338
811 + 31553527 = 31554338
1249 + 31553089 = 31554338

Showing the first eight; more decompositions exist.
