Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72474, here are decompositions:
- 5 + 72469 = 72474
- 7 + 72467 = 72474
- 13 + 72461 = 72474
- 43 + 72431 = 72474
- 53 + 72421 = 72474
- 107 + 72367 = 72474
- 137 + 72337 = 72474
- 167 + 72307 = 72474
Showing the first eight; more decompositions exist.
