Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931542, here are decompositions:

5 + 931537 = 931542
13 + 931529 = 931542
43 + 931499 = 931542
179 + 931363 = 931542
191 + 931351 = 931542
223 + 931319 = 931542
229 + 931313 = 931542
233 + 931309 = 931542

Showing the first eight; more decompositions exist.
