Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626240, here are decompositions:
- 7 + 31626233 = 31626240
- 11 + 31626229 = 31626240
- 31 + 31626209 = 31626240
- 43 + 31626197 = 31626240
- 47 + 31626193 = 31626240
- 73 + 31626167 = 31626240
- 109 + 31626131 = 31626240
- 131 + 31626109 = 31626240
Showing the first eight; more decompositions exist.
