Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042664, here are decompositions:

31 + 1042633 = 1042664
67 + 1042597 = 1042664
283 + 1042381 = 1042664
307 + 1042357 = 1042664
331 + 1042333 = 1042664
397 + 1042267 = 1042664
421 + 1042243 = 1042664
523 + 1042141 = 1042664

Showing the first eight; more decompositions exist.
