Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115722, here are decompositions:
- 29 + 115693 = 115722
- 43 + 115679 = 115722
- 59 + 115663 = 115722
- 109 + 115613 = 115722
- 151 + 115571 = 115722
- 199 + 115523 = 115722
- 223 + 115499 = 115722
- 251 + 115471 = 115722
Showing the first eight; more decompositions exist.
