Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708972, here are decompositions:

3 + 8708969 = 8708972
61 + 8708911 = 8708972
79 + 8708893 = 8708972
241 + 8708731 = 8708972
271 + 8708701 = 8708972
463 + 8708509 = 8708972
523 + 8708449 = 8708972
829 + 8708143 = 8708972

Showing the first eight; more decompositions exist.
