Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47426, here are decompositions:
- 7 + 47419 = 47426
- 19 + 47407 = 47426
- 37 + 47389 = 47426
- 73 + 47353 = 47426
- 109 + 47317 = 47426
- 139 + 47287 = 47426
- 157 + 47269 = 47426
- 277 + 47149 = 47426
Showing the first eight; more decompositions exist.
