Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991652, here are decompositions:

19 + 991633 = 991652
31 + 991621 = 991652
73 + 991579 = 991652
199 + 991453 = 991652
223 + 991429 = 991652
271 + 991381 = 991652
379 + 991273 = 991652
523 + 991129 = 991652

Showing the first eight; more decompositions exist.
