Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543602, here are decompositions:

23 + 31543579 = 31543602
31 + 31543571 = 31543602
59 + 31543543 = 31543602
71 + 31543531 = 31543602
73 + 31543529 = 31543602
113 + 31543489 = 31543602
149 + 31543453 = 31543602
151 + 31543451 = 31543602

Showing the first eight; more decompositions exist.
