Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28454, here are decompositions:
- 7 + 28447 = 28454
- 43 + 28411 = 28454
- 61 + 28393 = 28454
- 67 + 28387 = 28454
- 103 + 28351 = 28454
- 157 + 28297 = 28454
- 271 + 28183 = 28454
- 331 + 28123 = 28454
Showing the first eight; more decompositions exist.
