Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527174, here are decompositions:
- 17 + 31527157 = 31527174
- 23 + 31527151 = 31527174
- 31 + 31527143 = 31527174
- 43 + 31527131 = 31527174
- 67 + 31527107 = 31527174
- 97 + 31527077 = 31527174
- 127 + 31527047 = 31527174
- 157 + 31527017 = 31527174
Showing the first eight; more decompositions exist.
