Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63442, here are decompositions:
- 3 + 63439 = 63442
- 23 + 63419 = 63442
- 53 + 63389 = 63442
- 89 + 63353 = 63442
- 131 + 63311 = 63442
- 263 + 63179 = 63442
- 293 + 63149 = 63442
- 311 + 63131 = 63442
Showing the first eight; more decompositions exist.
