Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527582, here are decompositions:

5 + 31527577 = 31527582
13 + 31527569 = 31527582
41 + 31527541 = 31527582
59 + 31527523 = 31527582
61 + 31527521 = 31527582
83 + 31527499 = 31527582
101 + 31527481 = 31527582
193 + 31527389 = 31527582

Showing the first eight; more decompositions exist.
