Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4442, here are decompositions:
- 19 + 4423 = 4442
- 79 + 4363 = 4442
- 103 + 4339 = 4442
- 181 + 4261 = 4442
- 199 + 4243 = 4442
- 211 + 4231 = 4442
- 223 + 4219 = 4442
- 241 + 4201 = 4442
Showing the first eight; more decompositions exist.
