Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135372, here are decompositions:
- 5 + 135367 = 135372
- 19 + 135353 = 135372
- 23 + 135349 = 135372
- 43 + 135329 = 135372
- 53 + 135319 = 135372
- 71 + 135301 = 135372
- 89 + 135283 = 135372
- 101 + 135271 = 135372
Showing the first eight; more decompositions exist.
