Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47142, here are decompositions:
- 5 + 47137 = 47142
- 13 + 47129 = 47142
- 19 + 47123 = 47142
- 23 + 47119 = 47142
- 31 + 47111 = 47142
- 83 + 47059 = 47142
- 101 + 47041 = 47142
- 149 + 46993 = 47142
Showing the first eight; more decompositions exist.
