Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022488, here are decompositions:

59 + 1022429 = 1022488
101 + 1022387 = 1022488
107 + 1022381 = 1022488
197 + 1022291 = 1022488
239 + 1022249 = 1022488
251 + 1022237 = 1022488
347 + 1022141 = 1022488
359 + 1022129 = 1022488

Showing the first eight; more decompositions exist.
