Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722082, here are decompositions:

3 + 8722079 = 8722082
73 + 8722009 = 8722082
199 + 8721883 = 8722082
409 + 8721673 = 8722082
541 + 8721541 = 8722082
571 + 8721511 = 8722082
601 + 8721481 = 8722082
613 + 8721469 = 8722082

Showing the first eight; more decompositions exist.
