Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506060, here are decompositions:

29 + 31506031 = 31506060
31 + 31506029 = 31506060
67 + 31505993 = 31506060
71 + 31505989 = 31506060
101 + 31505959 = 31506060
137 + 31505923 = 31506060
139 + 31505921 = 31506060
151 + 31505909 = 31506060

Showing the first eight; more decompositions exist.
