Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739942, here are decompositions:
- 5 + 8739937 = 8739942
- 23 + 8739919 = 8739942
- 31 + 8739911 = 8739942
- 41 + 8739901 = 8739942
- 59 + 8739883 = 8739942
- 73 + 8739869 = 8739942
- 131 + 8739811 = 8739942
- 139 + 8739803 = 8739942
Showing the first eight; more decompositions exist.
