Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942040, here are decompositions:

3 + 942037 = 942040
23 + 942017 = 942040
41 + 941999 = 942040
59 + 941981 = 942040
107 + 941933 = 942040
137 + 941903 = 942040
179 + 941861 = 942040
227 + 941813 = 942040

Showing the first eight; more decompositions exist.
