Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051240, here are decompositions:

59 + 1051181 = 1051240
83 + 1051157 = 1051240
89 + 1051151 = 1051240
101 + 1051139 = 1051240
233 + 1051007 = 1051240
263 + 1050977 = 1051240
353 + 1050887 = 1051240
389 + 1050851 = 1051240

Showing the first eight; more decompositions exist.
