Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87912, here are decompositions:
- 31 + 87881 = 87912
- 43 + 87869 = 87912
- 59 + 87853 = 87912
- 79 + 87833 = 87912
- 101 + 87811 = 87912
- 109 + 87803 = 87912
- 173 + 87739 = 87912
- 191 + 87721 = 87912
Showing the first eight; more decompositions exist.
