Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569016, here are decompositions:
- 47 + 31568969 = 31569016
- 107 + 31568909 = 31569016
- 137 + 31568879 = 31569016
- 173 + 31568843 = 31569016
- 293 + 31568723 = 31569016
- 359 + 31568657 = 31569016
- 593 + 31568423 = 31569016
- 599 + 31568417 = 31569016
Showing the first eight; more decompositions exist.
