Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47120, here are decompositions:
- 61 + 47059 = 47120
- 79 + 47041 = 47120
- 103 + 47017 = 47120
- 127 + 46993 = 47120
- 163 + 46957 = 47120
- 313 + 46807 = 47120
- 349 + 46771 = 47120
- 373 + 46747 = 47120
Showing the first eight; more decompositions exist.
