Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148912, here are decompositions:
- 53 + 148859 = 148912
- 59 + 148853 = 148912
- 83 + 148829 = 148912
- 131 + 148781 = 148912
- 149 + 148763 = 148912
- 191 + 148721 = 148912
- 443 + 148469 = 148912
- 509 + 148403 = 148912
Showing the first eight; more decompositions exist.
