Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482962, here are decompositions:

73 + 31482889 = 31482962
103 + 31482859 = 31482962
139 + 31482823 = 31482962
163 + 31482799 = 31482962
331 + 31482631 = 31482962
349 + 31482613 = 31482962
463 + 31482499 = 31482962
523 + 31482439 = 31482962

Showing the first eight; more decompositions exist.
