Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486602, here are decompositions:

31 + 31486571 = 31486602
53 + 31486549 = 31486602
73 + 31486529 = 31486602
109 + 31486493 = 31486602
139 + 31486463 = 31486602
149 + 31486453 = 31486602
151 + 31486451 = 31486602
179 + 31486423 = 31486602

Showing the first eight; more decompositions exist.
