Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100898, here are decompositions:

97 + 100801 = 100898
151 + 100747 = 100898
157 + 100741 = 100898
199 + 100699 = 100898
229 + 100669 = 100898
277 + 100621 = 100898
307 + 100591 = 100898
349 + 100549 = 100898

Showing the first eight; more decompositions exist.
