Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990700, here are decompositions:

101 + 990599 = 990700
107 + 990593 = 990700
197 + 990503 = 990700
311 + 990389 = 990700
317 + 990383 = 990700
419 + 990281 = 990700
461 + 990239 = 990700
521 + 990179 = 990700

Showing the first eight; more decompositions exist.
