Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999488, here are decompositions:

37 + 999451 = 999488
157 + 999331 = 999488
181 + 999307 = 999488
271 + 999217 = 999488
307 + 999181 = 999488
397 + 999091 = 999488
421 + 999067 = 999488
439 + 999049 = 999488

Showing the first eight; more decompositions exist.
