Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931442, here are decompositions:

79 + 931363 = 931442
139 + 931303 = 931442
229 + 931213 = 931442
313 + 931129 = 931442
439 + 931003 = 931442
601 + 930841 = 931442
823 + 930619 = 931442
859 + 930583 = 931442

Showing the first eight; more decompositions exist.
