Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559318, here are decompositions:
- 67 + 31559251 = 31559318
- 79 + 31559239 = 31559318
- 157 + 31559161 = 31559318
- 379 + 31558939 = 31559318
- 421 + 31558897 = 31559318
- 487 + 31558831 = 31559318
- 499 + 31558819 = 31559318
- 547 + 31558771 = 31559318
Showing the first eight; more decompositions exist.
