Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142272, here are decompositions:
- 41 + 142231 = 142272
- 61 + 142211 = 142272
- 79 + 142193 = 142272
- 83 + 142189 = 142272
- 89 + 142183 = 142272
- 103 + 142169 = 142272
- 113 + 142159 = 142272
- 149 + 142123 = 142272
Showing the first eight; more decompositions exist.
