Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709940, here are decompositions:

11 + 8709929 = 8709940
101 + 8709839 = 8709940
227 + 8709713 = 8709940
263 + 8709677 = 8709940
293 + 8709647 = 8709940
353 + 8709587 = 8709940
431 + 8709509 = 8709940
479 + 8709461 = 8709940

Showing the first eight; more decompositions exist.
