Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931730, here are decompositions:

3 + 931727 = 931730
73 + 931657 = 931730
109 + 931621 = 931730
157 + 931573 = 931730
193 + 931537 = 931730
313 + 931417 = 931730
367 + 931363 = 931730
379 + 931351 = 931730

Showing the first eight; more decompositions exist.
