Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479060, here are decompositions:

29 + 31479031 = 31479060
43 + 31479017 = 31479060
59 + 31479001 = 31479060
101 + 31478959 = 31479060
103 + 31478957 = 31479060
127 + 31478933 = 31479060
149 + 31478911 = 31479060
229 + 31478831 = 31479060

Showing the first eight; more decompositions exist.
