Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990274, here are decompositions:

137 + 990137 = 990274
251 + 990023 = 990274
293 + 989981 = 990274
353 + 989921 = 990274
401 + 989873 = 990274
443 + 989831 = 990274
491 + 989783 = 990274
521 + 989753 = 990274

Showing the first eight; more decompositions exist.
