Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564958, here are decompositions:
- 31 + 31564927 = 31564958
- 37 + 31564921 = 31564958
- 67 + 31564891 = 31564958
- 79 + 31564879 = 31564958
- 109 + 31564849 = 31564958
- 127 + 31564831 = 31564958
- 151 + 31564807 = 31564958
- 367 + 31564591 = 31564958
Showing the first eight; more decompositions exist.
