Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479004, here are decompositions:

3 + 31479001 = 31479004
47 + 31478957 = 31479004
71 + 31478933 = 31479004
173 + 31478831 = 31479004
197 + 31478807 = 31479004
521 + 31478483 = 31479004
593 + 31478411 = 31479004
653 + 31478351 = 31479004

Showing the first eight; more decompositions exist.
