Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702942, here are decompositions:

103 + 8702839 = 8702942
109 + 8702833 = 8702942
139 + 8702803 = 8702942
211 + 8702731 = 8702942
349 + 8702593 = 8702942
373 + 8702569 = 8702942
439 + 8702503 = 8702942
571 + 8702371 = 8702942

Showing the first eight; more decompositions exist.
