Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47738, here are decompositions:
- 37 + 47701 = 47738
- 79 + 47659 = 47738
- 109 + 47629 = 47738
- 139 + 47599 = 47738
- 157 + 47581 = 47738
- 211 + 47527 = 47738
- 241 + 47497 = 47738
- 307 + 47431 = 47738
Showing the first eight; more decompositions exist.
