Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739816, here are decompositions:
- 5 + 8739811 = 8739816
- 13 + 8739803 = 8739816
- 47 + 8739769 = 8739816
- 67 + 8739749 = 8739816
- 103 + 8739713 = 8739816
- 149 + 8739667 = 8739816
- 179 + 8739637 = 8739816
- 193 + 8739623 = 8739816
Showing the first eight; more decompositions exist.
