Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489094, here are decompositions:
- 3 + 31489091 = 31489094
- 31 + 31489063 = 31489094
- 67 + 31489027 = 31489094
- 103 + 31488991 = 31489094
- 163 + 31488931 = 31489094
- 463 + 31488631 = 31489094
- 547 + 31488547 = 31489094
- 601 + 31488493 = 31489094
Showing the first eight; more decompositions exist.
