Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155376, here are decompositions:
- 5 + 155371 = 155376
- 43 + 155333 = 155376
- 59 + 155317 = 155376
- 73 + 155303 = 155376
- 107 + 155269 = 155376
- 157 + 155219 = 155376
- 167 + 155209 = 155376
- 173 + 155203 = 155376
Showing the first eight; more decompositions exist.
