Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981794, here are decompositions:

97 + 981697 = 981794
103 + 981691 = 981794
157 + 981637 = 981794
193 + 981601 = 981794
271 + 981523 = 981794
277 + 981517 = 981794
313 + 981481 = 981794
397 + 981397 = 981794

Showing the first eight; more decompositions exist.
