Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482002, here are decompositions:

103 + 31481899 = 31482002
151 + 31481851 = 31482002
271 + 31481731 = 31482002
379 + 31481623 = 31482002
523 + 31481479 = 31482002
571 + 31481431 = 31482002
613 + 31481389 = 31482002
619 + 31481383 = 31482002

Showing the first eight; more decompositions exist.
