Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100894, here are decompositions:

41 + 100853 = 100894
47 + 100847 = 100894
71 + 100823 = 100894
83 + 100811 = 100894
107 + 100787 = 100894
191 + 100703 = 100894
281 + 100613 = 100894
347 + 100547 = 100894

Showing the first eight; more decompositions exist.
