Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742338, here are decompositions:

79 + 8742259 = 8742338
151 + 8742187 = 8742338
181 + 8742157 = 8742338
271 + 8742067 = 8742338
349 + 8741989 = 8742338
499 + 8741839 = 8742338
541 + 8741797 = 8742338
859 + 8741479 = 8742338

Showing the first eight; more decompositions exist.
