Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128362, here are decompositions:
- 11 + 128351 = 128362
- 23 + 128339 = 128362
- 41 + 128321 = 128362
- 71 + 128291 = 128362
- 89 + 128273 = 128362
- 149 + 128213 = 128362
- 173 + 128189 = 128362
- 251 + 128111 = 128362
Showing the first eight; more decompositions exist.
