Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942812, here are decompositions:

103 + 942709 = 942812
151 + 942661 = 942812
229 + 942583 = 942812
271 + 942541 = 942812
373 + 942439 = 942812
379 + 942433 = 942812
499 + 942313 = 942812
613 + 942199 = 942812

Showing the first eight; more decompositions exist.
