Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20070, here are decompositions:
- 7 + 20063 = 20070
- 19 + 20051 = 20070
- 23 + 20047 = 20070
- 41 + 20029 = 20070
- 47 + 20023 = 20070
- 59 + 20011 = 20070
- 73 + 19997 = 20070
- 79 + 19991 = 20070
Showing the first eight; more decompositions exist.
