Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74428, here are decompositions:
- 17 + 74411 = 74428
- 47 + 74381 = 74428
- 71 + 74357 = 74428
- 131 + 74297 = 74428
- 149 + 74279 = 74428
- 197 + 74231 = 74428
- 227 + 74201 = 74428
- 239 + 74189 = 74428
Showing the first eight; more decompositions exist.
