Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446648, here are decompositions:
- 7 + 31446641 = 31446648
- 41 + 31446607 = 31446648
- 157 + 31446491 = 31446648
- 281 + 31446367 = 31446648
- 307 + 31446341 = 31446648
- 397 + 31446251 = 31446648
- 419 + 31446229 = 31446648
- 421 + 31446227 = 31446648
Showing the first eight; more decompositions exist.
