Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500492, here are decompositions:

5 + 31500487 = 31500492
29 + 31500463 = 31500492
41 + 31500451 = 31500492
73 + 31500419 = 31500492
109 + 31500383 = 31500492
113 + 31500379 = 31500492
131 + 31500361 = 31500492
139 + 31500353 = 31500492

Showing the first eight; more decompositions exist.
