Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739140, here are decompositions:

13 + 8739127 = 8739140
43 + 8739097 = 8739140
61 + 8739079 = 8739140
139 + 8739001 = 8739140
211 + 8738929 = 8739140
331 + 8738809 = 8739140
373 + 8738767 = 8739140
433 + 8738707 = 8739140

Showing the first eight; more decompositions exist.
