Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739490, here are decompositions:

59 + 8739431 = 8739490
101 + 8739389 = 8739490
131 + 8739359 = 8739490
191 + 8739299 = 8739490
281 + 8739209 = 8739490
293 + 8739197 = 8739490
467 + 8739023 = 8739490
647 + 8738843 = 8739490

Showing the first eight; more decompositions exist.
