Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947378, here are decompositions:

37 + 947341 = 947378
79 + 947299 = 947378
139 + 947239 = 947378
181 + 947197 = 947378
241 + 947137 = 947378
409 + 946969 = 947378
577 + 946801 = 947378
661 + 946717 = 947378

Showing the first eight; more decompositions exist.
