Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86904, here are decompositions:
- 43 + 86861 = 86904
- 47 + 86857 = 86904
- 53 + 86851 = 86904
- 61 + 86843 = 86904
- 67 + 86837 = 86904
- 137 + 86767 = 86904
- 151 + 86753 = 86904
- 193 + 86711 = 86904
Showing the first eight; more decompositions exist.
