Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47402, here are decompositions:
- 13 + 47389 = 47402
- 109 + 47293 = 47402
- 151 + 47251 = 47402
- 181 + 47221 = 47402
- 241 + 47161 = 47402
- 283 + 47119 = 47402
- 409 + 46993 = 47402
- 541 + 46861 = 47402
Showing the first eight; more decompositions exist.
