Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83978, here are decompositions:
- 67 + 83911 = 83978
- 109 + 83869 = 83978
- 241 + 83737 = 83978
- 277 + 83701 = 83978
- 337 + 83641 = 83978
- 421 + 83557 = 83978
- 541 + 83437 = 83978
- 547 + 83431 = 83978
Showing the first eight; more decompositions exist.
