Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482902, here are decompositions:

13 + 31482889 = 31482902
43 + 31482859 = 31482902
79 + 31482823 = 31482902
103 + 31482799 = 31482902
193 + 31482709 = 31482902
271 + 31482631 = 31482902
463 + 31482439 = 31482902
631 + 31482271 = 31482902

Showing the first eight; more decompositions exist.
