Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523582, here are decompositions:

3 + 31523579 = 31523582
43 + 31523539 = 31523582
61 + 31523521 = 31523582
109 + 31523473 = 31523582
163 + 31523419 = 31523582
331 + 31523251 = 31523582
373 + 31523209 = 31523582
421 + 31523161 = 31523582

Showing the first eight; more decompositions exist.
