Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100884, here are decompositions:

31 + 100853 = 100884
37 + 100847 = 100884
61 + 100823 = 100884
73 + 100811 = 100884
83 + 100801 = 100884
97 + 100787 = 100884
137 + 100747 = 100884
151 + 100733 = 100884

Showing the first eight; more decompositions exist.
