Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47154, here are decompositions:
- 5 + 47149 = 47154
- 7 + 47147 = 47154
- 11 + 47143 = 47154
- 17 + 47137 = 47154
- 31 + 47123 = 47154
- 43 + 47111 = 47154
- 61 + 47093 = 47154
- 67 + 47087 = 47154
Showing the first eight; more decompositions exist.
