Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991702, here are decompositions:

59 + 991643 = 991702
83 + 991619 = 991702
191 + 991511 = 991702
293 + 991409 = 991702
359 + 991343 = 991702
389 + 991313 = 991702
479 + 991223 = 991702
521 + 991181 = 991702

Showing the first eight; more decompositions exist.
