Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479184, here are decompositions:

53 + 31479131 = 31479184
83 + 31479101 = 31479184
101 + 31479083 = 31479184
167 + 31479017 = 31479184
227 + 31478957 = 31479184
251 + 31478933 = 31479184
353 + 31478831 = 31479184
617 + 31478567 = 31479184

Showing the first eight; more decompositions exist.
