Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47012, here are decompositions:
- 19 + 46993 = 47012
- 79 + 46933 = 47012
- 151 + 46861 = 47012
- 181 + 46831 = 47012
- 193 + 46819 = 47012
- 241 + 46771 = 47012
- 331 + 46681 = 47012
- 349 + 46663 = 47012
Showing the first eight; more decompositions exist.
