Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582424, here are decompositions:

7 + 31582417 = 31582424
103 + 31582321 = 31582424
157 + 31582267 = 31582424
241 + 31582183 = 31582424
331 + 31582093 = 31582424
397 + 31582027 = 31582424
421 + 31582003 = 31582424
463 + 31581961 = 31582424

Showing the first eight; more decompositions exist.
