Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947742, here are decompositions:

13 + 947729 = 947742
23 + 947719 = 947742
31 + 947711 = 947742
83 + 947659 = 947742
101 + 947641 = 947742
139 + 947603 = 947742
163 + 947579 = 947742
181 + 947561 = 947742

Showing the first eight; more decompositions exist.
