Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472248, here are decompositions:
- 47 + 31472201 = 31472248
- 89 + 31472159 = 31472248
- 179 + 31472069 = 31472248
- 257 + 31471991 = 31472248
- 281 + 31471967 = 31472248
- 347 + 31471901 = 31472248
- 449 + 31471799 = 31472248
- 461 + 31471787 = 31472248
Showing the first eight; more decompositions exist.
