Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040650, here are decompositions:

53 + 1040597 = 1040650
71 + 1040579 = 1040650
167 + 1040483 = 1040650
239 + 1040411 = 1040650
263 + 1040387 = 1040650
269 + 1040381 = 1040650
311 + 1040339 = 1040650
431 + 1040219 = 1040650

Showing the first eight; more decompositions exist.
