Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055660, here are decompositions:

157 + 1055503 = 1055660
223 + 1055437 = 1055660
313 + 1055347 = 1055660
409 + 1055251 = 1055660
523 + 1055137 = 1055660
547 + 1055113 = 1055660
577 + 1055083 = 1055660
643 + 1055017 = 1055660

Showing the first eight; more decompositions exist.
