Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523862, here are decompositions:

11 + 31523851 = 31523862
23 + 31523839 = 31523862
59 + 31523803 = 31523862
61 + 31523801 = 31523862
101 + 31523761 = 31523862
109 + 31523753 = 31523862
113 + 31523749 = 31523862
193 + 31523669 = 31523862

Showing the first eight; more decompositions exist.
