Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61320, here are decompositions:
- 23 + 61297 = 61320
- 29 + 61291 = 61320
- 37 + 61283 = 61320
- 59 + 61261 = 61320
- 67 + 61253 = 61320
- 89 + 61231 = 61320
- 97 + 61223 = 61320
- 109 + 61211 = 61320
Showing the first eight; more decompositions exist.
