Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719520, here are decompositions:

37 + 8719483 = 8719520
79 + 8719441 = 8719520
193 + 8719327 = 8719520
307 + 8719213 = 8719520
379 + 8719141 = 8719520
421 + 8719099 = 8719520
463 + 8719057 = 8719520
499 + 8719021 = 8719520

Showing the first eight; more decompositions exist.
