Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991262, here are decompositions:

61 + 991201 = 991262
193 + 991069 = 991262
199 + 991063 = 991262
373 + 990889 = 991262
421 + 990841 = 991262
463 + 990799 = 991262
619 + 990643 = 991262
631 + 990631 = 991262

Showing the first eight; more decompositions exist.
