Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981692, here are decompositions:

199 + 981493 = 981692
211 + 981481 = 981692
241 + 981451 = 981692
373 + 981319 = 981692
409 + 981283 = 981692
421 + 981271 = 981692
541 + 981151 = 981692
601 + 981091 = 981692

Showing the first eight; more decompositions exist.
