Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32442, here are decompositions:
- 13 + 32429 = 32442
- 19 + 32423 = 32442
- 29 + 32413 = 32442
- 31 + 32411 = 32442
- 41 + 32401 = 32442
- 61 + 32381 = 32442
- 71 + 32371 = 32442
- 73 + 32369 = 32442
Showing the first eight; more decompositions exist.
