Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100888, here are decompositions:

41 + 100847 = 100888
59 + 100829 = 100888
89 + 100799 = 100888
101 + 100787 = 100888
239 + 100649 = 100888
419 + 100469 = 100888
509 + 100379 = 100888
617 + 100271 = 100888

Showing the first eight; more decompositions exist.
