Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022372, here are decompositions:

31 + 1022341 = 1022372
163 + 1022209 = 1022372
181 + 1022191 = 1022372
193 + 1022179 = 1022372
313 + 1022059 = 1022372
409 + 1021963 = 1022372
523 + 1021849 = 1022372
541 + 1021831 = 1022372

Showing the first eight; more decompositions exist.
