Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562798, here are decompositions:

19 + 31562779 = 31562798
31 + 31562767 = 31562798
61 + 31562737 = 31562798
181 + 31562617 = 31562798
331 + 31562467 = 31562798
349 + 31562449 = 31562798
367 + 31562431 = 31562798
409 + 31562389 = 31562798

Showing the first eight; more decompositions exist.
