Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482730, here are decompositions:

23 + 31482707 = 31482730
47 + 31482683 = 31482730
89 + 31482641 = 31482730
113 + 31482617 = 31482730
131 + 31482599 = 31482730
179 + 31482551 = 31482730
449 + 31482281 = 31482730
557 + 31482173 = 31482730

Showing the first eight; more decompositions exist.
