Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720126, here are decompositions:

7 + 8720119 = 8720126
13 + 8720113 = 8720126
127 + 8719999 = 8720126
139 + 8719987 = 8720126
223 + 8719903 = 8720126
307 + 8719819 = 8720126
313 + 8719813 = 8720126
379 + 8719747 = 8720126

Showing the first eight; more decompositions exist.
