Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579426, here are decompositions:
- 83 + 31579343 = 31579426
- 149 + 31579277 = 31579426
- 233 + 31579193 = 31579426
- 239 + 31579187 = 31579426
- 293 + 31579133 = 31579426
- 317 + 31579109 = 31579426
- 353 + 31579073 = 31579426
- 479 + 31578947 = 31579426
Showing the first eight; more decompositions exist.
