Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734490, here are decompositions:

7 + 8734483 = 8734490
73 + 8734417 = 8734490
97 + 8734393 = 8734490
103 + 8734387 = 8734490
139 + 8734351 = 8734490
277 + 8734213 = 8734490
337 + 8734153 = 8734490
397 + 8734093 = 8734490

Showing the first eight; more decompositions exist.
