Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31190, here are decompositions:
- 7 + 31183 = 31190
- 13 + 31177 = 31190
- 31 + 31159 = 31190
- 37 + 31153 = 31190
- 43 + 31147 = 31190
- 67 + 31123 = 31190
- 109 + 31081 = 31190
- 127 + 31063 = 31190
Showing the first eight; more decompositions exist.
