Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004642, here are decompositions:

43 + 1004599 = 1004642
181 + 1004461 = 1004642
193 + 1004449 = 1004642
241 + 1004401 = 1004642
271 + 1004371 = 1004642
349 + 1004293 = 1004642
409 + 1004233 = 1004642
421 + 1004221 = 1004642

Showing the first eight; more decompositions exist.
