Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942578, here are decompositions:

37 + 942541 = 942578
139 + 942439 = 942578
211 + 942367 = 942578
277 + 942301 = 942578
331 + 942247 = 942578
379 + 942199 = 942578
409 + 942169 = 942578
487 + 942091 = 942578

Showing the first eight; more decompositions exist.
