Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479702, here are decompositions:

5 + 31479697 = 31479702
31 + 31479671 = 31479702
53 + 31479649 = 31479702
83 + 31479619 = 31479702
109 + 31479593 = 31479702
113 + 31479589 = 31479702
151 + 31479551 = 31479702
211 + 31479491 = 31479702

Showing the first eight; more decompositions exist.
