Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702072, here are decompositions:

73 + 8701999 = 8702072
139 + 8701933 = 8702072
151 + 8701921 = 8702072
199 + 8701873 = 8702072
283 + 8701789 = 8702072
331 + 8701741 = 8702072
349 + 8701723 = 8702072
541 + 8701531 = 8702072

Showing the first eight; more decompositions exist.
