Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2242, here are decompositions:
- 3 + 2239 = 2242
- 5 + 2237 = 2242
- 29 + 2213 = 2242
- 89 + 2153 = 2242
- 101 + 2141 = 2242
- 113 + 2129 = 2242
- 131 + 2111 = 2242
- 173 + 2069 = 2242
Showing the first eight; more decompositions exist.
