Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142848, here are decompositions:
- 7 + 142841 = 142848
- 11 + 142837 = 142848
- 37 + 142811 = 142848
- 59 + 142789 = 142848
- 61 + 142787 = 142848
- 89 + 142759 = 142848
- 137 + 142711 = 142848
- 149 + 142699 = 142848
Showing the first eight; more decompositions exist.
