Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540452, here are decompositions:

11 + 31540441 = 31540452
89 + 31540363 = 31540452
109 + 31540343 = 31540452
113 + 31540339 = 31540452
191 + 31540261 = 31540452
211 + 31540241 = 31540452
239 + 31540213 = 31540452
241 + 31540211 = 31540452

Showing the first eight; more decompositions exist.
