Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135490, here are decompositions:

11 + 135479 = 135490
23 + 135467 = 135490
29 + 135461 = 135490
41 + 135449 = 135490
59 + 135431 = 135490
101 + 135389 = 135490
137 + 135353 = 135490
233 + 135257 = 135490

Showing the first eight; more decompositions exist.
