Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148980, here are decompositions:
- 19 + 148961 = 148980
- 23 + 148957 = 148980
- 31 + 148949 = 148980
- 47 + 148933 = 148980
- 53 + 148927 = 148980
- 59 + 148921 = 148980
- 67 + 148913 = 148980
- 89 + 148891 = 148980
Showing the first eight; more decompositions exist.
