Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739020, here are decompositions:

13 + 8739007 = 8739020
19 + 8739001 = 8739020
139 + 8738881 = 8739020
181 + 8738839 = 8739020
211 + 8738809 = 8739020
307 + 8738713 = 8739020
313 + 8738707 = 8739020
349 + 8738671 = 8739020

Showing the first eight; more decompositions exist.
