Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739900, here are decompositions:
- 17 + 8739883 = 8739900
- 23 + 8739877 = 8739900
- 31 + 8739869 = 8739900
- 73 + 8739827 = 8739900
- 79 + 8739821 = 8739900
- 89 + 8739811 = 8739900
- 97 + 8739803 = 8739900
- 131 + 8739769 = 8739900
Showing the first eight; more decompositions exist.
