Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149138, here are decompositions:
- 19 + 149119 = 149138
- 37 + 149101 = 149138
- 61 + 149077 = 149138
- 79 + 149059 = 149138
- 127 + 149011 = 149138
- 181 + 148957 = 149138
- 211 + 148927 = 149138
- 271 + 148867 = 149138
Showing the first eight; more decompositions exist.
