Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523892, here are decompositions:

11 + 31523881 = 31523892
41 + 31523851 = 31523892
53 + 31523839 = 31523892
89 + 31523803 = 31523892
131 + 31523761 = 31523892
139 + 31523753 = 31523892
223 + 31523669 = 31523892
233 + 31523659 = 31523892

Showing the first eight; more decompositions exist.
