Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100868, here are decompositions:

67 + 100801 = 100868
127 + 100741 = 100868
199 + 100669 = 100868
277 + 100591 = 100868
331 + 100537 = 100868
349 + 100519 = 100868
367 + 100501 = 100868
409 + 100459 = 100868

Showing the first eight; more decompositions exist.
