Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56438, here are decompositions:
- 7 + 56431 = 56438
- 37 + 56401 = 56438
- 61 + 56377 = 56438
- 79 + 56359 = 56438
- 127 + 56311 = 56438
- 139 + 56299 = 56438
- 199 + 56239 = 56438
- 229 + 56209 = 56438
Showing the first eight; more decompositions exist.
