Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991482, here are decompositions:

29 + 991453 = 991482
53 + 991429 = 991482
73 + 991409 = 991482
101 + 991381 = 991482
139 + 991343 = 991482
281 + 991201 = 991482
311 + 991171 = 991482
353 + 991129 = 991482

Showing the first eight; more decompositions exist.
