Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72354, here are decompositions:
- 13 + 72341 = 72354
- 17 + 72337 = 72354
- 41 + 72313 = 72354
- 47 + 72307 = 72354
- 67 + 72287 = 72354
- 83 + 72271 = 72354
- 101 + 72253 = 72354
- 103 + 72251 = 72354
Showing the first eight; more decompositions exist.
