Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746142, here are decompositions:

73 + 8746069 = 8746142
79 + 8746063 = 8746142
151 + 8745991 = 8746142
313 + 8745829 = 8746142
439 + 8745703 = 8746142
463 + 8745679 = 8746142
571 + 8745571 = 8746142
619 + 8745523 = 8746142

Showing the first eight; more decompositions exist.
