Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637902, here are decompositions:

73 + 8637829 = 8637902
283 + 8637619 = 8637902
379 + 8637523 = 8637902
409 + 8637493 = 8637902
421 + 8637481 = 8637902
523 + 8637379 = 8637902
601 + 8637301 = 8637902
613 + 8637289 = 8637902

Showing the first eight; more decompositions exist.
