Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492192, here are decompositions:

29 + 31492163 = 31492192
101 + 31492091 = 31492192
113 + 31492079 = 31492192
131 + 31492061 = 31492192
233 + 31491959 = 31492192
311 + 31491881 = 31492192
401 + 31491791 = 31492192
443 + 31491749 = 31492192

Showing the first eight; more decompositions exist.
