Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35280, here are decompositions:
- 13 + 35267 = 35280
- 23 + 35257 = 35280
- 29 + 35251 = 35280
- 53 + 35227 = 35280
- 59 + 35221 = 35280
- 79 + 35201 = 35280
- 109 + 35171 = 35280
- 127 + 35153 = 35280
Showing the first eight; more decompositions exist.
