Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739738, here are decompositions:
- 17 + 8739721 = 8739738
- 67 + 8739671 = 8739738
- 71 + 8739667 = 8739738
- 101 + 8739637 = 8739738
- 131 + 8739607 = 8739738
- 239 + 8739499 = 8739738
- 257 + 8739481 = 8739738
- 307 + 8739431 = 8739738
Showing the first eight; more decompositions exist.
