Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563452, here are decompositions:

61 + 31563391 = 31563452
103 + 31563349 = 31563452
199 + 31563253 = 31563452
379 + 31563073 = 31563452
409 + 31563043 = 31563452
421 + 31563031 = 31563452
439 + 31563013 = 31563452
541 + 31562911 = 31563452

Showing the first eight; more decompositions exist.
