Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87474, here are decompositions:
- 31 + 87443 = 87474
- 41 + 87433 = 87474
- 47 + 87427 = 87474
- 53 + 87421 = 87474
- 67 + 87407 = 87474
- 71 + 87403 = 87474
- 137 + 87337 = 87474
- 151 + 87323 = 87474
Showing the first eight; more decompositions exist.
