Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543948, here are decompositions:

41 + 31543907 = 31543948
71 + 31543877 = 31543948
89 + 31543859 = 31543948
101 + 31543847 = 31543948
131 + 31543817 = 31543948
179 + 31543769 = 31543948
197 + 31543751 = 31543948
251 + 31543697 = 31543948

Showing the first eight; more decompositions exist.
