Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562852, here are decompositions:

3 + 31562849 = 31562852
73 + 31562779 = 31562852
229 + 31562623 = 31562852
241 + 31562611 = 31562852
421 + 31562431 = 31562852
463 + 31562389 = 31562852
523 + 31562329 = 31562852
571 + 31562281 = 31562852

Showing the first eight; more decompositions exist.
