Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742308, here are decompositions:

139 + 8742169 = 8742308
151 + 8742157 = 8742308
241 + 8742067 = 8742308
271 + 8742037 = 8742308
331 + 8741977 = 8742308
397 + 8741911 = 8742308
787 + 8741521 = 8742308
829 + 8741479 = 8742308

Showing the first eight; more decompositions exist.
