Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573434, here are decompositions:

7 + 31573427 = 31573434
41 + 31573393 = 31573434
43 + 31573391 = 31573434
71 + 31573363 = 31573434
73 + 31573361 = 31573434
157 + 31573277 = 31573434
173 + 31573261 = 31573434
181 + 31573253 = 31573434

Showing the first eight; more decompositions exist.
