Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99172, here are decompositions:
- 23 + 99149 = 99172
- 41 + 99131 = 99172
- 53 + 99119 = 99172
- 83 + 99089 = 99172
- 89 + 99083 = 99172
- 131 + 99041 = 99172
- 149 + 99023 = 99172
- 173 + 98999 = 99172
Showing the first eight; more decompositions exist.
