Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558802, here are decompositions:

3 + 31558799 = 31558802
13 + 31558789 = 31558802
31 + 31558771 = 31558802
43 + 31558759 = 31558802
61 + 31558741 = 31558802
73 + 31558729 = 31558802
109 + 31558693 = 31558802
139 + 31558663 = 31558802

Showing the first eight; more decompositions exist.
