Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004872, here are decompositions:

149 + 1004723 = 1004872
311 + 1004561 = 1004872
389 + 1004483 = 1004872
419 + 1004453 = 1004872
431 + 1004441 = 1004872
443 + 1004429 = 1004872
509 + 1004363 = 1004872
569 + 1004303 = 1004872

Showing the first eight; more decompositions exist.
