Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546178, here are decompositions:
- 19 + 31546159 = 31546178
- 67 + 31546111 = 31546178
- 109 + 31546069 = 31546178
- 277 + 31545901 = 31546178
- 337 + 31545841 = 31546178
- 439 + 31545739 = 31546178
- 571 + 31545607 = 31546178
- 691 + 31545487 = 31546178
Showing the first eight; more decompositions exist.
