Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576602, here are decompositions:

19 + 31576583 = 31576602
23 + 31576579 = 31576602
53 + 31576549 = 31576602
61 + 31576541 = 31576602
73 + 31576529 = 31576602
149 + 31576453 = 31576602
163 + 31576439 = 31576602
191 + 31576411 = 31576602

Showing the first eight; more decompositions exist.
