Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527842, here are decompositions:

13 + 31527829 = 31527842
61 + 31527781 = 31527842
139 + 31527703 = 31527842
499 + 31527343 = 31527842
631 + 31527211 = 31527842
691 + 31527151 = 31527842
733 + 31527109 = 31527842
1033 + 31526809 = 31527842

Showing the first eight; more decompositions exist.
