Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137722, here are decompositions:
- 23 + 137699 = 137722
- 83 + 137639 = 137722
- 89 + 137633 = 137722
- 149 + 137573 = 137722
- 239 + 137483 = 137722
- 269 + 137453 = 137722
- 353 + 137369 = 137722
- 359 + 137363 = 137722
Showing the first eight; more decompositions exist.
