Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534860, here are decompositions:
- 29 + 31534831 = 31534860
- 41 + 31534819 = 31534860
- 59 + 31534801 = 31534860
- 61 + 31534799 = 31534860
- 73 + 31534787 = 31534860
- 103 + 31534757 = 31534860
- 107 + 31534753 = 31534860
- 109 + 31534751 = 31534860
Showing the first eight; more decompositions exist.
