Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532248, here are decompositions:
- 29 + 31532219 = 31532248
- 107 + 31532141 = 31532248
- 131 + 31532117 = 31532248
- 227 + 31532021 = 31532248
- 281 + 31531967 = 31532248
- 317 + 31531931 = 31532248
- 431 + 31531817 = 31532248
- 521 + 31531727 = 31532248
Showing the first eight; more decompositions exist.
