Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141872, here are decompositions:
- 19 + 141853 = 141872
- 43 + 141829 = 141872
- 61 + 141811 = 141872
- 79 + 141793 = 141872
- 103 + 141769 = 141872
- 163 + 141709 = 141872
- 193 + 141679 = 141872
- 223 + 141649 = 141872
Showing the first eight; more decompositions exist.
