Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563032, here are decompositions:

3 + 31563029 = 31563032
19 + 31563013 = 31563032
31 + 31563001 = 31563032
73 + 31562959 = 31563032
349 + 31562683 = 31563032
409 + 31562623 = 31563032
421 + 31562611 = 31563032
439 + 31562593 = 31563032

Showing the first eight; more decompositions exist.
