Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534430, here are decompositions:
- 3 + 31534427 = 31534430
- 7 + 31534423 = 31534430
- 19 + 31534411 = 31534430
- 61 + 31534369 = 31534430
- 97 + 31534333 = 31534430
- 199 + 31534231 = 31534430
- 313 + 31534117 = 31534430
- 373 + 31534057 = 31534430
Showing the first eight; more decompositions exist.
