Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018622, here are decompositions:

79 + 1018543 = 1018622
109 + 1018513 = 1018622
151 + 1018471 = 1018622
193 + 1018429 = 1018622
211 + 1018411 = 1018622
313 + 1018309 = 1018622
331 + 1018291 = 1018622
421 + 1018201 = 1018622

Showing the first eight; more decompositions exist.
