Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055840, here are decompositions:

13 + 1055827 = 1055840
31 + 1055809 = 1055840
103 + 1055737 = 1055840
109 + 1055731 = 1055840
127 + 1055713 = 1055840
151 + 1055689 = 1055840
229 + 1055611 = 1055840
337 + 1055503 = 1055840

Showing the first eight; more decompositions exist.
