Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488124, here are decompositions:

23 + 31488101 = 31488124
53 + 31488071 = 31488124
71 + 31488053 = 31488124
131 + 31487993 = 31488124
167 + 31487957 = 31488124
251 + 31487873 = 31488124
257 + 31487867 = 31488124
443 + 31487681 = 31488124

Showing the first eight; more decompositions exist.
