Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72360, here are decompositions:
- 7 + 72353 = 72360
- 19 + 72341 = 72360
- 23 + 72337 = 72360
- 47 + 72313 = 72360
- 53 + 72307 = 72360
- 73 + 72287 = 72360
- 83 + 72277 = 72360
- 89 + 72271 = 72360
Showing the first eight; more decompositions exist.
