Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739890, here are decompositions:
- 7 + 8739883 = 8739890
- 13 + 8739877 = 8739890
- 67 + 8739823 = 8739890
- 79 + 8739811 = 8739890
- 151 + 8739739 = 8739890
- 223 + 8739667 = 8739890
- 283 + 8739607 = 8739890
- 307 + 8739583 = 8739890
Showing the first eight; more decompositions exist.
