Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593870, here are decompositions:
- 31 + 31593839 = 31593870
- 37 + 31593833 = 31593870
- 73 + 31593797 = 31593870
- 83 + 31593787 = 31593870
- 103 + 31593767 = 31593870
- 107 + 31593763 = 31593870
- 149 + 31593721 = 31593870
- 151 + 31593719 = 31593870
Showing the first eight; more decompositions exist.
