Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83872, here are decompositions:
- 3 + 83869 = 83872
- 29 + 83843 = 83872
- 59 + 83813 = 83872
- 233 + 83639 = 83872
- 251 + 83621 = 83872
- 263 + 83609 = 83872
- 281 + 83591 = 83872
- 293 + 83579 = 83872
Showing the first eight; more decompositions exist.
