Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148790, here are decompositions:
- 7 + 148783 = 148790
- 43 + 148747 = 148790
- 67 + 148723 = 148790
- 79 + 148711 = 148790
- 97 + 148693 = 148790
- 127 + 148663 = 148790
- 151 + 148639 = 148790
- 157 + 148633 = 148790
Showing the first eight; more decompositions exist.
