Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582358, here are decompositions:

37 + 31582321 = 31582358
109 + 31582249 = 31582358
151 + 31582207 = 31582358
331 + 31582027 = 31582358
337 + 31582021 = 31582358
397 + 31581961 = 31582358
499 + 31581859 = 31582358
541 + 31581817 = 31582358

Showing the first eight; more decompositions exist.
