Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545474, here are decompositions:
- 5 + 31545469 = 31545474
- 67 + 31545407 = 31545474
- 73 + 31545401 = 31545474
- 83 + 31545391 = 31545474
- 101 + 31545373 = 31545474
- 131 + 31545343 = 31545474
- 151 + 31545323 = 31545474
- 157 + 31545317 = 31545474
Showing the first eight; more decompositions exist.
