Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558346, here are decompositions:

19 + 31558327 = 31558346
37 + 31558309 = 31558346
139 + 31558207 = 31558346
199 + 31558147 = 31558346
283 + 31558063 = 31558346
307 + 31558039 = 31558346
349 + 31557997 = 31558346
409 + 31557937 = 31558346

Showing the first eight; more decompositions exist.
