Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425738, here are decompositions:
- 131 + 2147425607 = 2147425738
- 179 + 2147425559 = 2147425738
- 197 + 2147425541 = 2147425738
- 281 + 2147425457 = 2147425738
- 389 + 2147425349 = 2147425738
- 569 + 2147425169 = 2147425738
- 599 + 2147425139 = 2147425738
- 617 + 2147425121 = 2147425738
Showing the first eight; more decompositions exist.
