Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47102, here are decompositions:
- 43 + 47059 = 47102
- 61 + 47041 = 47102
- 109 + 46993 = 47102
- 241 + 46861 = 47102
- 271 + 46831 = 47102
- 283 + 46819 = 47102
- 331 + 46771 = 47102
- 379 + 46723 = 47102
Showing the first eight; more decompositions exist.
