Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492060, here are decompositions:

29 + 31492031 = 31492060
71 + 31491989 = 31492060
101 + 31491959 = 31492060
167 + 31491893 = 31492060
179 + 31491881 = 31492060
269 + 31491791 = 31492060
311 + 31491749 = 31492060
401 + 31491659 = 31492060

Showing the first eight; more decompositions exist.
