Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739390, here are decompositions:

31 + 8739359 = 8739390
41 + 8739349 = 8739390
53 + 8739337 = 8739390
59 + 8739331 = 8739390
109 + 8739281 = 8739390
181 + 8739209 = 8739390
193 + 8739197 = 8739390
197 + 8739193 = 8739390

Showing the first eight; more decompositions exist.
