Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29872, here are decompositions:
- 5 + 29867 = 29872
- 53 + 29819 = 29872
- 83 + 29789 = 29872
- 113 + 29759 = 29872
- 131 + 29741 = 29872
- 149 + 29723 = 29872
- 239 + 29633 = 29872
- 389 + 29483 = 29872
Showing the first eight; more decompositions exist.
