Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739428, here are decompositions:

31 + 8739397 = 8739428
37 + 8739391 = 8739428
79 + 8739349 = 8739428
97 + 8739331 = 8739428
241 + 8739187 = 8739428
331 + 8739097 = 8739428
349 + 8739079 = 8739428
421 + 8739007 = 8739428

Showing the first eight; more decompositions exist.
