Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47100, here are decompositions:
- 7 + 47093 = 47100
- 13 + 47087 = 47100
- 41 + 47059 = 47100
- 43 + 47057 = 47100
- 59 + 47041 = 47100
- 83 + 47017 = 47100
- 103 + 46997 = 47100
- 107 + 46993 = 47100
Showing the first eight; more decompositions exist.
