Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739242, here are decompositions:

73 + 8739169 = 8739242
79 + 8739163 = 8739242
163 + 8739079 = 8739242
241 + 8739001 = 8739242
313 + 8738929 = 8739242
433 + 8738809 = 8739242
571 + 8738671 = 8739242
601 + 8738641 = 8739242

Showing the first eight; more decompositions exist.
