Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548876, here are decompositions:

5 + 31548871 = 31548876
19 + 31548857 = 31548876
53 + 31548823 = 31548876
59 + 31548817 = 31548876
109 + 31548767 = 31548876
113 + 31548763 = 31548876
127 + 31548749 = 31548876
137 + 31548739 = 31548876

Showing the first eight; more decompositions exist.
