Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938258, here are decompositions:

7 + 938251 = 938258
151 + 938107 = 938258
199 + 938059 = 938258
241 + 938017 = 938258
331 + 937927 = 938258
367 + 937891 = 938258
439 + 937819 = 938258
457 + 937801 = 938258

Showing the first eight; more decompositions exist.
