Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121944, here are decompositions:
- 7 + 121937 = 121944
- 13 + 121931 = 121944
- 23 + 121921 = 121944
- 61 + 121883 = 121944
- 101 + 121843 = 121944
- 157 + 121787 = 121944
- 181 + 121763 = 121944
- 223 + 121721 = 121944
Showing the first eight; more decompositions exist.
