Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931228, here are decompositions:

29 + 931199 = 931228
47 + 931181 = 931228
59 + 931169 = 931228
101 + 931127 = 931228
131 + 931097 = 931228
239 + 930989 = 931228
251 + 930977 = 931228
317 + 930911 = 931228

Showing the first eight; more decompositions exist.
