Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47412, here are decompositions:
- 5 + 47407 = 47412
- 23 + 47389 = 47412
- 31 + 47381 = 47412
- 59 + 47353 = 47412
- 61 + 47351 = 47412
- 73 + 47339 = 47412
- 103 + 47309 = 47412
- 109 + 47303 = 47412
Showing the first eight; more decompositions exist.
