Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592944, here are decompositions:
- 23 + 31592921 = 31592944
- 101 + 31592843 = 31592944
- 197 + 31592747 = 31592944
- 281 + 31592663 = 31592944
- 293 + 31592651 = 31592944
- 491 + 31592453 = 31592944
- 521 + 31592423 = 31592944
- 587 + 31592357 = 31592944
Showing the first eight; more decompositions exist.
