Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100208, here are decompositions:

19 + 100189 = 100208
79 + 100129 = 100208
139 + 100069 = 100208
151 + 100057 = 100208
307 + 99901 = 100208
331 + 99877 = 100208
337 + 99871 = 100208
349 + 99859 = 100208

Showing the first eight; more decompositions exist.
