Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100178, here are decompositions:

109 + 100069 = 100178
271 + 99907 = 100178
277 + 99901 = 100178
307 + 99871 = 100178
349 + 99829 = 100178
457 + 99721 = 100178
499 + 99679 = 100178
571 + 99607 = 100178

Showing the first eight; more decompositions exist.
