Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940628, here are decompositions:

79 + 940549 = 940628
97 + 940531 = 940628
127 + 940501 = 940628
151 + 940477 = 940628
229 + 940399 = 940628
277 + 940351 = 940628
331 + 940297 = 940628
349 + 940279 = 940628

Showing the first eight; more decompositions exist.
