Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606602, here are decompositions:

19 + 31606583 = 31606602
23 + 31606579 = 31606602
43 + 31606559 = 31606602
59 + 31606543 = 31606602
61 + 31606541 = 31606602
73 + 31606529 = 31606602
103 + 31606499 = 31606602
109 + 31606493 = 31606602

Showing the first eight; more decompositions exist.
