Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479232, here are decompositions:
- 101 + 31479131 = 31479232
- 131 + 31479101 = 31479232
- 149 + 31479083 = 31479232
- 263 + 31478969 = 31479232
- 401 + 31478831 = 31479232
- 593 + 31478639 = 31479232
- 761 + 31478471 = 31479232
- 821 + 31478411 = 31479232
Showing the first eight; more decompositions exist.
