Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519026, here are decompositions:

37 + 31518989 = 31519026
73 + 31518953 = 31519026
103 + 31518923 = 31519026
113 + 31518913 = 31519026
127 + 31518899 = 31519026
157 + 31518869 = 31519026
163 + 31518863 = 31519026
167 + 31518859 = 31519026

Showing the first eight; more decompositions exist.
