Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483126, here are decompositions:

29 + 31483097 = 31483126
149 + 31482977 = 31483126
179 + 31482947 = 31483126
293 + 31482833 = 31483126
347 + 31482779 = 31483126
383 + 31482743 = 31483126
419 + 31482707 = 31483126
443 + 31482683 = 31483126

Showing the first eight; more decompositions exist.
