Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590956, here are decompositions:
- 13 + 31590943 = 31590956
- 79 + 31590877 = 31590956
- 109 + 31590847 = 31590956
- 193 + 31590763 = 31590956
- 223 + 31590733 = 31590956
- 307 + 31590649 = 31590956
- 367 + 31590589 = 31590956
- 373 + 31590583 = 31590956
Showing the first eight; more decompositions exist.
