Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38442, here are decompositions:
- 11 + 38431 = 38442
- 71 + 38371 = 38442
- 109 + 38333 = 38442
- 113 + 38329 = 38442
- 139 + 38303 = 38442
- 181 + 38261 = 38442
- 211 + 38231 = 38442
- 223 + 38219 = 38442
Showing the first eight; more decompositions exist.
