Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128348, here are decompositions:
- 7 + 128341 = 128348
- 37 + 128311 = 128348
- 61 + 128287 = 128348
- 109 + 128239 = 128348
- 127 + 128221 = 128348
- 229 + 128119 = 128348
- 397 + 127951 = 128348
- 499 + 127849 = 128348
Showing the first eight; more decompositions exist.
