Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38842, here are decompositions:
- 3 + 38839 = 38842
- 59 + 38783 = 38842
- 113 + 38729 = 38842
- 131 + 38711 = 38842
- 149 + 38693 = 38842
- 173 + 38669 = 38842
- 191 + 38651 = 38842
- 233 + 38609 = 38842
Showing the first eight; more decompositions exist.
