Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148940, here are decompositions:
- 7 + 148933 = 148940
- 13 + 148927 = 148940
- 19 + 148921 = 148940
- 67 + 148873 = 148940
- 73 + 148867 = 148940
- 79 + 148861 = 148940
- 157 + 148783 = 148940
- 193 + 148747 = 148940
Showing the first eight; more decompositions exist.
