Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460038, here are decompositions:

89 + 31459949 = 31460038
101 + 31459937 = 31460038
107 + 31459931 = 31460038
179 + 31459859 = 31460038
191 + 31459847 = 31460038
359 + 31459679 = 31460038
419 + 31459619 = 31460038
521 + 31459517 = 31460038

Showing the first eight; more decompositions exist.
