Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611964, here are decompositions:

3 + 8611961 = 8611964
61 + 8611903 = 8611964
73 + 8611891 = 8611964
181 + 8611783 = 8611964
241 + 8611723 = 8611964
331 + 8611633 = 8611964
367 + 8611597 = 8611964
433 + 8611531 = 8611964

Showing the first eight; more decompositions exist.
