Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942872, here are decompositions:

3 + 942869 = 942872
13 + 942859 = 942872
19 + 942853 = 942872
61 + 942811 = 942872
109 + 942763 = 942872
163 + 942709 = 942872
181 + 942691 = 942872
211 + 942661 = 942872

Showing the first eight; more decompositions exist.
