Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131574, here are decompositions:

13 + 131561 = 131574
31 + 131543 = 131574
67 + 131507 = 131574
73 + 131501 = 131574
97 + 131477 = 131574
127 + 131447 = 131574
137 + 131437 = 131574
193 + 131381 = 131574

Showing the first eight; more decompositions exist.
