Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534830, here are decompositions:
- 11 + 31534819 = 31534830
- 29 + 31534801 = 31534830
- 31 + 31534799 = 31534830
- 43 + 31534787 = 31534830
- 73 + 31534757 = 31534830
- 79 + 31534751 = 31534830
- 101 + 31534729 = 31534830
- 139 + 31534691 = 31534830
Showing the first eight; more decompositions exist.
