Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022248, here are decompositions:

5 + 1022243 = 1022248
11 + 1022237 = 1022248
47 + 1022201 = 1022248
107 + 1022141 = 1022248
449 + 1021799 = 1022248
587 + 1021661 = 1022248
677 + 1021571 = 1022248
761 + 1021487 = 1022248

Showing the first eight; more decompositions exist.
