Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541412, here are decompositions:
- 11 + 31541401 = 31541412
- 13 + 31541399 = 31541412
- 53 + 31541359 = 31541412
- 131 + 31541281 = 31541412
- 179 + 31541233 = 31541412
- 233 + 31541179 = 31541412
- 239 + 31541173 = 31541412
- 251 + 31541161 = 31541412
Showing the first eight; more decompositions exist.
