Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142234, here are decompositions:
- 3 + 142231 = 142234
- 11 + 142223 = 142234
- 17 + 142217 = 142234
- 23 + 142211 = 142234
- 41 + 142193 = 142234
- 83 + 142151 = 142234
- 137 + 142097 = 142234
- 167 + 142067 = 142234
Showing the first eight; more decompositions exist.
