Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945380, here are decompositions:

3 + 945377 = 945380
13 + 945367 = 945380
31 + 945349 = 945380
229 + 945151 = 945380
277 + 945103 = 945380
349 + 945031 = 945380
487 + 944893 = 945380
523 + 944857 = 945380

Showing the first eight; more decompositions exist.
