Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148770, here are decompositions:
- 7 + 148763 = 148770
- 23 + 148747 = 148770
- 43 + 148727 = 148770
- 47 + 148723 = 148770
- 59 + 148711 = 148770
- 79 + 148691 = 148770
- 101 + 148669 = 148770
- 103 + 148667 = 148770
Showing the first eight; more decompositions exist.
