Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446790, here are decompositions:
- 29 + 31446761 = 31446790
- 41 + 31446749 = 31446790
- 47 + 31446743 = 31446790
- 101 + 31446689 = 31446790
- 149 + 31446641 = 31446790
- 197 + 31446593 = 31446790
- 227 + 31446563 = 31446790
- 233 + 31446557 = 31446790
Showing the first eight; more decompositions exist.
