Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988574, here are decompositions:

3 + 988571 = 988574
73 + 988501 = 988574
157 + 988417 = 988574
277 + 988297 = 988574
331 + 988243 = 988574
337 + 988237 = 988574
463 + 988111 = 988574
523 + 988051 = 988574

Showing the first eight; more decompositions exist.
