Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689890, here are decompositions:
- 37 + 8689853 = 8689890
- 47 + 8689843 = 8689890
- 67 + 8689823 = 8689890
- 73 + 8689817 = 8689890
- 113 + 8689777 = 8689890
- 137 + 8689753 = 8689890
- 163 + 8689727 = 8689890
- 179 + 8689711 = 8689890
Showing the first eight; more decompositions exist.
