Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742322, here are decompositions:

5 + 8742317 = 8742322
59 + 8742263 = 8742322
263 + 8742059 = 8742322
311 + 8742011 = 8742322
389 + 8741933 = 8742322
461 + 8741861 = 8742322
509 + 8741813 = 8742322
521 + 8741801 = 8742322

Showing the first eight; more decompositions exist.
