Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563002, here are decompositions:

19 + 31562983 = 31563002
43 + 31562959 = 31563002
223 + 31562779 = 31563002
379 + 31562623 = 31563002
409 + 31562593 = 31563002
571 + 31562431 = 31563002
613 + 31562389 = 31563002
673 + 31562329 = 31563002

Showing the first eight; more decompositions exist.
