Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940838, here are decompositions:

37 + 940801 = 940838
79 + 940759 = 940838
307 + 940531 = 940838
337 + 940501 = 940838
439 + 940399 = 940838
487 + 940351 = 940838
541 + 940297 = 940838
751 + 940087 = 940838

Showing the first eight; more decompositions exist.
