Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532488, here are decompositions:
- 11 + 31532477 = 31532488
- 59 + 31532429 = 31532488
- 149 + 31532339 = 31532488
- 227 + 31532261 = 31532488
- 269 + 31532219 = 31532488
- 347 + 31532141 = 31532488
- 467 + 31532021 = 31532488
- 521 + 31531967 = 31532488
Showing the first eight; more decompositions exist.
