Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480174, here are decompositions:

71 + 31480103 = 31480174
83 + 31480091 = 31480174
113 + 31480061 = 31480174
227 + 31479947 = 31480174
293 + 31479881 = 31480174
317 + 31479857 = 31480174
353 + 31479821 = 31480174
431 + 31479743 = 31480174

Showing the first eight; more decompositions exist.
