Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128276, here are decompositions:
- 3 + 128273 = 128276
- 19 + 128257 = 128276
- 37 + 128239 = 128276
- 73 + 128203 = 128276
- 103 + 128173 = 128276
- 157 + 128119 = 128276
- 163 + 128113 = 128276
- 223 + 128053 = 128276
Showing the first eight; more decompositions exist.
