Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544648, here are decompositions:
- 61 + 31544587 = 31544648
- 97 + 31544551 = 31544648
- 139 + 31544509 = 31544648
- 277 + 31544371 = 31544648
- 337 + 31544311 = 31544648
- 367 + 31544281 = 31544648
- 571 + 31544077 = 31544648
- 607 + 31544041 = 31544648
Showing the first eight; more decompositions exist.
