Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725942, here are decompositions:

11 + 8725931 = 8725942
101 + 8725841 = 8725942
311 + 8725631 = 8725942
419 + 8725523 = 8725942
431 + 8725511 = 8725942
443 + 8725499 = 8725942
461 + 8725481 = 8725942
479 + 8725463 = 8725942

Showing the first eight; more decompositions exist.
