Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541268, here are decompositions:

89 + 31541179 = 31541268
107 + 31541161 = 31541268
127 + 31541141 = 31541268
139 + 31541129 = 31541268
151 + 31541117 = 31541268
167 + 31541101 = 31541268
197 + 31541071 = 31541268
229 + 31541039 = 31541268

Showing the first eight; more decompositions exist.
