Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735438, here are decompositions:

67 + 8735371 = 8735438
79 + 8735359 = 8735438
97 + 8735341 = 8735438
139 + 8735299 = 8735438
241 + 8735197 = 8735438
409 + 8735029 = 8735438
457 + 8734981 = 8735438
619 + 8734819 = 8735438

Showing the first eight; more decompositions exist.
