Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991762, here are decompositions:

11 + 991751 = 991762
29 + 991733 = 991762
59 + 991703 = 991762
251 + 991511 = 991762
263 + 991499 = 991762
269 + 991493 = 991762
353 + 991409 = 991762
419 + 991343 = 991762

Showing the first eight; more decompositions exist.
