Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479482, here are decompositions:

43 + 31479439 = 31479482
61 + 31479421 = 31479482
193 + 31479289 = 31479482
211 + 31479271 = 31479482
241 + 31479241 = 31479482
409 + 31479073 = 31479482
421 + 31479061 = 31479482
499 + 31478983 = 31479482

Showing the first eight; more decompositions exist.
