Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537554, here are decompositions:
- 7 + 31537547 = 31537554
- 11 + 31537543 = 31537554
- 47 + 31537507 = 31537554
- 73 + 31537481 = 31537554
- 163 + 31537391 = 31537554
- 227 + 31537327 = 31537554
- 241 + 31537313 = 31537554
- 281 + 31537273 = 31537554
Showing the first eight; more decompositions exist.
