Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629430, here are decompositions:

97 + 8629333 = 8629430
151 + 8629279 = 8629430
307 + 8629123 = 8629430
367 + 8629063 = 8629430
421 + 8629009 = 8629430
457 + 8628973 = 8629430
463 + 8628967 = 8629430
541 + 8628889 = 8629430

Showing the first eight; more decompositions exist.
