Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719904, here are decompositions:

31 + 8719873 = 8719904
73 + 8719831 = 8719904
103 + 8719801 = 8719904
157 + 8719747 = 8719904
223 + 8719681 = 8719904
241 + 8719663 = 8719904
313 + 8719591 = 8719904
331 + 8719573 = 8719904

Showing the first eight; more decompositions exist.
