Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7272, here are decompositions:
- 19 + 7253 = 7272
- 29 + 7243 = 7272
- 43 + 7229 = 7272
- 53 + 7219 = 7272
- 59 + 7213 = 7272
- 61 + 7211 = 7272
- 79 + 7193 = 7272
- 113 + 7159 = 7272
Showing the first eight; more decompositions exist.
