Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708572, here are decompositions:

53 + 8708519 = 8708572
71 + 8708501 = 8708572
149 + 8708423 = 8708572
179 + 8708393 = 8708572
233 + 8708339 = 8708572
281 + 8708291 = 8708572
311 + 8708261 = 8708572
419 + 8708153 = 8708572

Showing the first eight; more decompositions exist.
