Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564236, here are decompositions:
- 7 + 31564229 = 31564236
- 29 + 31564207 = 31564236
- 73 + 31564163 = 31564236
- 79 + 31564157 = 31564236
- 89 + 31564147 = 31564236
- 97 + 31564139 = 31564236
- 103 + 31564133 = 31564236
- 107 + 31564129 = 31564236
Showing the first eight; more decompositions exist.
