Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38242, here are decompositions:
- 3 + 38239 = 38242
- 5 + 38237 = 38242
- 11 + 38231 = 38242
- 23 + 38219 = 38242
- 41 + 38201 = 38242
- 53 + 38189 = 38242
- 59 + 38183 = 38242
- 89 + 38153 = 38242
Showing the first eight; more decompositions exist.
