Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623402, here are decompositions:

83 + 8623319 = 8623402
149 + 8623253 = 8623402
383 + 8623019 = 8623402
419 + 8622983 = 8623402
443 + 8622959 = 8623402
479 + 8622923 = 8623402
719 + 8622683 = 8623402
839 + 8622563 = 8623402

Showing the first eight; more decompositions exist.
