Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991502, here are decompositions:

3 + 991499 = 991502
19 + 991483 = 991502
73 + 991429 = 991502
229 + 991273 = 991502
241 + 991261 = 991502
331 + 991171 = 991502
373 + 991129 = 991502
433 + 991069 = 991502

Showing the first eight; more decompositions exist.
