Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538802, here are decompositions:

13 + 31538789 = 31538802
23 + 31538779 = 31538802
59 + 31538743 = 31538802
73 + 31538729 = 31538802
83 + 31538719 = 31538802
89 + 31538713 = 31538802
109 + 31538693 = 31538802
131 + 31538671 = 31538802

Showing the first eight; more decompositions exist.
