Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101798, here are decompositions:

61 + 101737 = 101798
79 + 101719 = 101798
97 + 101701 = 101798
157 + 101641 = 101798
199 + 101599 = 101798
271 + 101527 = 101798
331 + 101467 = 101798
349 + 101449 = 101798

Showing the first eight; more decompositions exist.
