Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87058, here are decompositions:
- 17 + 87041 = 87058
- 47 + 87011 = 87058
- 89 + 86969 = 87058
- 107 + 86951 = 87058
- 131 + 86927 = 87058
- 197 + 86861 = 87058
- 347 + 86711 = 87058
- 431 + 86627 = 87058
Showing the first eight; more decompositions exist.
