Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83812, here are decompositions:
- 149 + 83663 = 83812
- 173 + 83639 = 83812
- 191 + 83621 = 83812
- 233 + 83579 = 83812
- 251 + 83561 = 83812
- 353 + 83459 = 83812
- 389 + 83423 = 83812
- 569 + 83243 = 83812
Showing the first eight; more decompositions exist.
