Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31226, here are decompositions:
- 3 + 31223 = 31226
- 7 + 31219 = 31226
- 37 + 31189 = 31226
- 43 + 31183 = 31226
- 67 + 31159 = 31226
- 73 + 31153 = 31226
- 79 + 31147 = 31226
- 103 + 31123 = 31226
Showing the first eight; more decompositions exist.
