Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554698, here are decompositions:

31 + 31554667 = 31554698
61 + 31554637 = 31554698
67 + 31554631 = 31554698
79 + 31554619 = 31554698
127 + 31554571 = 31554698
157 + 31554541 = 31554698
181 + 31554517 = 31554698
337 + 31554361 = 31554698

Showing the first eight; more decompositions exist.
