Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582514, here are decompositions:

43 + 31582471 = 31582514
97 + 31582417 = 31582514
181 + 31582333 = 31582514
193 + 31582321 = 31582514
307 + 31582207 = 31582514
331 + 31582183 = 31582514
421 + 31582093 = 31582514
487 + 31582027 = 31582514

Showing the first eight; more decompositions exist.
