Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543364, here are decompositions:

3 + 31543361 = 31543364
157 + 31543207 = 31543364
373 + 31542991 = 31543364
397 + 31542967 = 31543364
421 + 31542943 = 31543364
487 + 31542877 = 31543364
577 + 31542787 = 31543364
661 + 31542703 = 31543364

Showing the first eight; more decompositions exist.
