Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576452, here are decompositions:

13 + 31576439 = 31576452
41 + 31576411 = 31576452
43 + 31576409 = 31576452
79 + 31576373 = 31576452
101 + 31576351 = 31576452
163 + 31576289 = 31576452
191 + 31576261 = 31576452
199 + 31576253 = 31576452

Showing the first eight; more decompositions exist.
