Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540874, here are decompositions:
- 3 + 31540871 = 31540874
- 7 + 31540867 = 31540874
- 37 + 31540837 = 31540874
- 61 + 31540813 = 31540874
- 151 + 31540723 = 31540874
- 181 + 31540693 = 31540874
- 223 + 31540651 = 31540874
- 373 + 31540501 = 31540874
Showing the first eight; more decompositions exist.
