Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991802, here are decompositions:

61 + 991741 = 991802
79 + 991723 = 991802
109 + 991693 = 991802
139 + 991663 = 991802
151 + 991651 = 991802
181 + 991621 = 991802
199 + 991603 = 991802
223 + 991579 = 991802

Showing the first eight; more decompositions exist.
