Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938778, here are decompositions:

17 + 938761 = 938778
31 + 938747 = 938778
97 + 938681 = 938778
101 + 938677 = 938778
167 + 938611 = 938778
241 + 938537 = 938778
271 + 938507 = 938778
331 + 938447 = 938778

Showing the first eight; more decompositions exist.
