Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938480, here are decompositions:

43 + 938437 = 938480
139 + 938341 = 938480
157 + 938323 = 938480
223 + 938257 = 938480
229 + 938251 = 938480
373 + 938107 = 938480
397 + 938083 = 938480
409 + 938071 = 938480

Showing the first eight; more decompositions exist.
