Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479352, here are decompositions:

53 + 31479299 = 31479352
83 + 31479269 = 31479352
101 + 31479251 = 31479352
251 + 31479101 = 31479352
269 + 31479083 = 31479352
383 + 31478969 = 31479352
419 + 31478933 = 31479352
521 + 31478831 = 31479352

Showing the first eight; more decompositions exist.
