Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563704, here are decompositions:

103 + 31563601 = 31563704
241 + 31563463 = 31563704
313 + 31563391 = 31563704
421 + 31563283 = 31563704
541 + 31563163 = 31563704
577 + 31563127 = 31563704
631 + 31563073 = 31563704
661 + 31563043 = 31563704

Showing the first eight; more decompositions exist.
