Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99890, here are decompositions:
- 13 + 99877 = 99890
- 19 + 99871 = 99890
- 31 + 99859 = 99890
- 61 + 99829 = 99890
- 67 + 99823 = 99890
- 73 + 99817 = 99890
- 97 + 99793 = 99890
- 103 + 99787 = 99890
Showing the first eight; more decompositions exist.
