Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513072, here are decompositions:
- 5 + 513067 = 513072
- 13 + 513059 = 513072
- 19 + 513053 = 513072
- 31 + 513041 = 513072
- 41 + 513031 = 513072
- 59 + 513013 = 513072
- 71 + 513001 = 513072
- 73 + 512999 = 513072
Showing the first eight; more decompositions exist.
