Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47186, here are decompositions:
- 37 + 47149 = 47186
- 43 + 47143 = 47186
- 67 + 47119 = 47186
- 127 + 47059 = 47186
- 193 + 46993 = 47186
- 229 + 46957 = 47186
- 367 + 46819 = 47186
- 379 + 46807 = 47186
Showing the first eight; more decompositions exist.
