Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31010, here are decompositions:

61 + 30949 = 31010
73 + 30937 = 31010
79 + 30931 = 31010
139 + 30871 = 31010
151 + 30859 = 31010
157 + 30853 = 31010
181 + 30829 = 31010
193 + 30817 = 31010

Showing the first eight; more decompositions exist.
