Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87430, here are decompositions:
- 3 + 87427 = 87430
- 23 + 87407 = 87430
- 47 + 87383 = 87430
- 71 + 87359 = 87430
- 107 + 87323 = 87430
- 113 + 87317 = 87430
- 131 + 87299 = 87430
- 137 + 87293 = 87430
Showing the first eight; more decompositions exist.
