Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103442, here are decompositions:
- 19 + 103423 = 103442
- 43 + 103399 = 103442
- 109 + 103333 = 103442
- 151 + 103291 = 103442
- 211 + 103231 = 103442
- 271 + 103171 = 103442
- 349 + 103093 = 103442
- 373 + 103069 = 103442
Showing the first eight; more decompositions exist.
