Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582340, here are decompositions:

3 + 31582337 = 31582340
7 + 31582333 = 31582340
19 + 31582321 = 31582340
73 + 31582267 = 31582340
157 + 31582183 = 31582340
313 + 31582027 = 31582340
337 + 31582003 = 31582340
367 + 31581973 = 31582340

Showing the first eight; more decompositions exist.
