Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51722, here are decompositions:
- 3 + 51719 = 51722
- 31 + 51691 = 51722
- 43 + 51679 = 51722
- 109 + 51613 = 51722
- 211 + 51511 = 51722
- 241 + 51481 = 51722
- 283 + 51439 = 51722
- 373 + 51349 = 51722
Showing the first eight; more decompositions exist.
