Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460700, here are decompositions:

23 + 31460677 = 31460700
43 + 31460657 = 31460700
53 + 31460647 = 31460700
149 + 31460551 = 31460700
151 + 31460549 = 31460700
163 + 31460537 = 31460700
191 + 31460509 = 31460700
269 + 31460431 = 31460700

Showing the first eight; more decompositions exist.
