Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148764, here are decompositions:
- 17 + 148747 = 148764
- 37 + 148727 = 148764
- 41 + 148723 = 148764
- 43 + 148721 = 148764
- 53 + 148711 = 148764
- 71 + 148693 = 148764
- 73 + 148691 = 148764
- 97 + 148667 = 148764
Showing the first eight; more decompositions exist.
