Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86172, here are decompositions:
- 11 + 86161 = 86172
- 29 + 86143 = 86172
- 41 + 86131 = 86172
- 59 + 86113 = 86172
- 61 + 86111 = 86172
- 89 + 86083 = 86172
- 103 + 86069 = 86172
- 173 + 85999 = 86172
Showing the first eight; more decompositions exist.
