Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999590, here are decompositions:

37 + 999553 = 999590
61 + 999529 = 999590
139 + 999451 = 999590
157 + 999433 = 999590
283 + 999307 = 999590
373 + 999217 = 999590
409 + 999181 = 999590
421 + 999169 = 999590

Showing the first eight; more decompositions exist.
