Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425580, here are decompositions:
- 61 + 2147425519 = 2147425580
- 67 + 2147425513 = 2147425580
- 73 + 2147425507 = 2147425580
- 127 + 2147425453 = 2147425580
- 199 + 2147425381 = 2147425580
- 271 + 2147425309 = 2147425580
- 283 + 2147425297 = 2147425580
- 331 + 2147425249 = 2147425580
Showing the first eight; more decompositions exist.
