Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534958, here are decompositions:
- 79 + 31534879 = 31534958
- 127 + 31534831 = 31534958
- 139 + 31534819 = 31534958
- 157 + 31534801 = 31534958
- 229 + 31534729 = 31534958
- 307 + 31534651 = 31534958
- 397 + 31534561 = 31534958
- 457 + 31534501 = 31534958
Showing the first eight; more decompositions exist.
