Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588852, here are decompositions:
- 5 + 31588847 = 31588852
- 173 + 31588679 = 31588852
- 179 + 31588673 = 31588852
- 359 + 31588493 = 31588852
- 389 + 31588463 = 31588852
- 521 + 31588331 = 31588852
- 599 + 31588253 = 31588852
- 653 + 31588199 = 31588852
Showing the first eight; more decompositions exist.
