Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147442746, here are decompositions:
- 73 + 2147442673 = 2147442746
- 109 + 2147442637 = 2147442746
- 223 + 2147442523 = 2147442746
- 277 + 2147442469 = 2147442746
- 313 + 2147442433 = 2147442746
- 457 + 2147442289 = 2147442746
- 607 + 2147442139 = 2147442746
- 769 + 2147441977 = 2147442746
Showing the first eight; more decompositions exist.
