Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991592, here are decompositions:

13 + 991579 = 991592
61 + 991531 = 991592
109 + 991483 = 991592
139 + 991453 = 991592
163 + 991429 = 991592
211 + 991381 = 991592
331 + 991261 = 991592
421 + 991171 = 991592

Showing the first eight; more decompositions exist.
