Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931648, here are decompositions:

71 + 931577 = 931648
131 + 931517 = 931648
149 + 931499 = 931648
227 + 931421 = 931648
359 + 931289 = 931648
449 + 931199 = 931648
467 + 931181 = 931648
479 + 931169 = 931648

Showing the first eight; more decompositions exist.
