Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446672, here are decompositions:
- 31 + 31446641 = 31446672
- 79 + 31446593 = 31446672
- 109 + 31446563 = 31446672
- 139 + 31446533 = 31446672
- 181 + 31446491 = 31446672
- 211 + 31446461 = 31446672
- 233 + 31446439 = 31446672
- 311 + 31446361 = 31446672
Showing the first eight; more decompositions exist.
