Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739288, here are decompositions:

7 + 8739281 = 8739288
79 + 8739209 = 8739288
101 + 8739187 = 8739288
191 + 8739097 = 8739288
281 + 8739007 = 8739288
331 + 8738957 = 8739288
359 + 8738929 = 8739288
449 + 8738839 = 8739288

Showing the first eight; more decompositions exist.
