Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464600, here are decompositions:

19 + 31464581 = 31464600
23 + 31464577 = 31464600
29 + 31464571 = 31464600
43 + 31464557 = 31464600
53 + 31464547 = 31464600
107 + 31464493 = 31464600
137 + 31464463 = 31464600
149 + 31464451 = 31464600

Showing the first eight; more decompositions exist.
