Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479934, here are decompositions:

53 + 31479881 = 31479934
113 + 31479821 = 31479934
131 + 31479803 = 31479934
191 + 31479743 = 31479934
197 + 31479737 = 31479934
263 + 31479671 = 31479934
383 + 31479551 = 31479934
443 + 31479491 = 31479934

Showing the first eight; more decompositions exist.
