Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142224, here are decompositions:
- 7 + 142217 = 142224
- 13 + 142211 = 142224
- 31 + 142193 = 142224
- 41 + 142183 = 142224
- 67 + 142157 = 142224
- 73 + 142151 = 142224
- 101 + 142123 = 142224
- 113 + 142111 = 142224
Showing the first eight; more decompositions exist.
