Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72324, here are decompositions:
- 11 + 72313 = 72324
- 17 + 72307 = 72324
- 37 + 72287 = 72324
- 47 + 72277 = 72324
- 53 + 72271 = 72324
- 71 + 72253 = 72324
- 73 + 72251 = 72324
- 97 + 72227 = 72324
Showing the first eight; more decompositions exist.
