Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86430, here are decompositions:
- 7 + 86423 = 86430
- 17 + 86413 = 86430
- 31 + 86399 = 86430
- 41 + 86389 = 86430
- 59 + 86371 = 86430
- 61 + 86369 = 86430
- 73 + 86357 = 86430
- 79 + 86351 = 86430
Showing the first eight; more decompositions exist.
