Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720162, here are decompositions:

43 + 8720119 = 8720162
163 + 8719999 = 8720162
211 + 8719951 = 8720162
223 + 8719939 = 8720162
331 + 8719831 = 8720162
349 + 8719813 = 8720162
463 + 8719699 = 8720162
499 + 8719663 = 8720162

Showing the first eight; more decompositions exist.
