Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554748, here are decompositions:

89 + 31554659 = 31554748
107 + 31554641 = 31554748
131 + 31554617 = 31554748
179 + 31554569 = 31554748
347 + 31554401 = 31554748
461 + 31554287 = 31554748
569 + 31554179 = 31554748
587 + 31554161 = 31554748

Showing the first eight; more decompositions exist.
