Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538292, here are decompositions:

31 + 31538261 = 31538292
41 + 31538251 = 31538292
53 + 31538239 = 31538292
89 + 31538203 = 31538292
131 + 31538161 = 31538292
139 + 31538153 = 31538292
151 + 31538141 = 31538292
179 + 31538113 = 31538292

Showing the first eight; more decompositions exist.
