Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445852, here are decompositions:

3 + 31445849 = 31445852
19 + 31445833 = 31445852
211 + 31445641 = 31445852
241 + 31445611 = 31445852
313 + 31445539 = 31445852
409 + 31445443 = 31445852
421 + 31445431 = 31445852
433 + 31445419 = 31445852

Showing the first eight; more decompositions exist.
