Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534484, here are decompositions:

43 + 31534441 = 31534484
61 + 31534423 = 31534484
73 + 31534411 = 31534484
151 + 31534333 = 31534484
367 + 31534117 = 31534484
433 + 31534051 = 31534484
613 + 31533871 = 31534484
661 + 31533823 = 31534484

Showing the first eight; more decompositions exist.
