Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480048, here are decompositions:

29 + 31480019 = 31480048
101 + 31479947 = 31480048
167 + 31479881 = 31480048
191 + 31479857 = 31480048
227 + 31479821 = 31480048
311 + 31479737 = 31480048
401 + 31479647 = 31480048
491 + 31479557 = 31480048

Showing the first eight; more decompositions exist.
