Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148740, here are decompositions:
- 13 + 148727 = 148740
- 17 + 148723 = 148740
- 19 + 148721 = 148740
- 29 + 148711 = 148740
- 47 + 148693 = 148740
- 71 + 148669 = 148740
- 73 + 148667 = 148740
- 101 + 148639 = 148740
Showing the first eight; more decompositions exist.
