Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100908, here are decompositions:

61 + 100847 = 100908
79 + 100829 = 100908
97 + 100811 = 100908
107 + 100801 = 100908
109 + 100799 = 100908
139 + 100769 = 100908
167 + 100741 = 100908
239 + 100669 = 100908

Showing the first eight; more decompositions exist.
