Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167442, here are decompositions:
- 5 + 167437 = 167442
- 13 + 167429 = 167442
- 19 + 167423 = 167442
- 29 + 167413 = 167442
- 61 + 167381 = 167442
- 101 + 167341 = 167442
- 103 + 167339 = 167442
- 113 + 167329 = 167442
Showing the first eight; more decompositions exist.
