Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87974, here are decompositions:
- 13 + 87961 = 87974
- 31 + 87943 = 87974
- 43 + 87931 = 87974
- 97 + 87877 = 87974
- 163 + 87811 = 87974
- 181 + 87793 = 87974
- 223 + 87751 = 87974
- 277 + 87697 = 87974
Showing the first eight; more decompositions exist.
