Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29782, here are decompositions:
- 23 + 29759 = 29782
- 29 + 29753 = 29782
- 41 + 29741 = 29782
- 59 + 29723 = 29782
- 113 + 29669 = 29782
- 149 + 29633 = 29782
- 251 + 29531 = 29782
- 281 + 29501 = 29782
Showing the first eight; more decompositions exist.
