Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47124, here are decompositions:
- 5 + 47119 = 47124
- 13 + 47111 = 47124
- 31 + 47093 = 47124
- 37 + 47087 = 47124
- 67 + 47057 = 47124
- 73 + 47051 = 47124
- 83 + 47041 = 47124
- 107 + 47017 = 47124
Showing the first eight; more decompositions exist.
