Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554848, here are decompositions:

7 + 31554841 = 31554848
19 + 31554829 = 31554848
37 + 31554811 = 31554848
109 + 31554739 = 31554848
139 + 31554709 = 31554848
181 + 31554667 = 31554848
211 + 31554637 = 31554848
229 + 31554619 = 31554848

Showing the first eight; more decompositions exist.
