Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931238, here are decompositions:

109 + 931129 = 931238
151 + 931087 = 931238
307 + 930931 = 931238
349 + 930889 = 931238
379 + 930859 = 931238
397 + 930841 = 931238
421 + 930817 = 931238
571 + 930667 = 931238

Showing the first eight; more decompositions exist.
