Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991594, here are decompositions:

47 + 991547 = 991594
53 + 991541 = 991594
83 + 991511 = 991594
101 + 991493 = 991594
167 + 991427 = 991594
251 + 991343 = 991594
281 + 991313 = 991594
467 + 991127 = 991594

Showing the first eight; more decompositions exist.
