Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462524, here are decompositions:

17 + 31462507 = 31462524
43 + 31462481 = 31462524
53 + 31462471 = 31462524
73 + 31462451 = 31462524
83 + 31462441 = 31462524
151 + 31462373 = 31462524
167 + 31462357 = 31462524
173 + 31462351 = 31462524

Showing the first eight; more decompositions exist.
