Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543732, here are decompositions:

41 + 31543691 = 31543732
71 + 31543661 = 31543732
89 + 31543643 = 31543732
251 + 31543481 = 31543732
281 + 31543451 = 31543732
383 + 31543349 = 31543732
401 + 31543331 = 31543732
431 + 31543301 = 31543732

Showing the first eight; more decompositions exist.
