Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135378, here are decompositions:
- 11 + 135367 = 135378
- 29 + 135349 = 135378
- 31 + 135347 = 135378
- 59 + 135319 = 135378
- 97 + 135281 = 135378
- 101 + 135277 = 135378
- 107 + 135271 = 135378
- 137 + 135241 = 135378
Showing the first eight; more decompositions exist.
