Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973642, here are decompositions:
- 13 + 4294973629 = 4294973642
- 31 + 4294973611 = 4294973642
- 73 + 4294973569 = 4294973642
- 103 + 4294973539 = 4294973642
- 409 + 4294973233 = 4294973642
- 439 + 4294973203 = 4294973642
- 541 + 4294973101 = 4294973642
- 571 + 4294973071 = 4294973642
Showing the first eight; more decompositions exist.
