Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748942, here are decompositions:

53 + 8748889 = 8748942
61 + 8748881 = 8748942
89 + 8748853 = 8748942
101 + 8748841 = 8748942
131 + 8748811 = 8748942
199 + 8748743 = 8748942
211 + 8748731 = 8748942
229 + 8748713 = 8748942

Showing the first eight; more decompositions exist.
