Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623298, here are decompositions:

41 + 31623257 = 31623298
89 + 31623209 = 31623298
131 + 31623167 = 31623298
251 + 31623047 = 31623298
257 + 31623041 = 31623298
347 + 31622951 = 31623298
359 + 31622939 = 31623298
461 + 31622837 = 31623298

Showing the first eight; more decompositions exist.
