Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004890, here are decompositions:

17 + 1004873 = 1004890
167 + 1004723 = 1004890
233 + 1004657 = 1004890
239 + 1004651 = 1004890
353 + 1004537 = 1004890
389 + 1004501 = 1004890
449 + 1004441 = 1004890
461 + 1004429 = 1004890

Showing the first eight; more decompositions exist.
