Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148784, here are decompositions:
- 3 + 148781 = 148784
- 37 + 148747 = 148784
- 61 + 148723 = 148784
- 73 + 148711 = 148784
- 151 + 148633 = 148784
- 157 + 148627 = 148784
- 211 + 148573 = 148784
- 271 + 148513 = 148784
Showing the first eight; more decompositions exist.
