Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540302, here are decompositions:

5 + 31540297 = 31540302
41 + 31540261 = 31540302
61 + 31540241 = 31540302
89 + 31540213 = 31540302
113 + 31540189 = 31540302
139 + 31540163 = 31540302
179 + 31540123 = 31540302
193 + 31540109 = 31540302

Showing the first eight; more decompositions exist.
