Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558012, here are decompositions:
- 29 + 31557983 = 31558012
- 41 + 31557971 = 31558012
- 53 + 31557959 = 31558012
- 131 + 31557881 = 31558012
- 179 + 31557833 = 31558012
- 251 + 31557761 = 31558012
- 263 + 31557749 = 31558012
- 281 + 31557731 = 31558012
Showing the first eight; more decompositions exist.
