Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49972, here are decompositions:
- 29 + 49943 = 49972
- 53 + 49919 = 49972
- 101 + 49871 = 49972
- 149 + 49823 = 49972
- 233 + 49739 = 49972
- 359 + 49613 = 49972
- 443 + 49529 = 49972
- 449 + 49523 = 49972
Showing the first eight; more decompositions exist.
