Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128132, here are decompositions:
- 13 + 128119 = 128132
- 19 + 128113 = 128132
- 79 + 128053 = 128132
- 181 + 127951 = 128132
- 211 + 127921 = 128132
- 283 + 127849 = 128132
- 313 + 127819 = 128132
- 421 + 127711 = 128132
Showing the first eight; more decompositions exist.
