Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47570, here are decompositions:
- 7 + 47563 = 47570
- 37 + 47533 = 47570
- 43 + 47527 = 47570
- 73 + 47497 = 47570
- 79 + 47491 = 47570
- 139 + 47431 = 47570
- 151 + 47419 = 47570
- 163 + 47407 = 47570
Showing the first eight; more decompositions exist.
