Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535004, here are decompositions:

5 + 31534999 = 31535004
23 + 31534981 = 31535004
43 + 31534961 = 31535004
131 + 31534873 = 31535004
173 + 31534831 = 31535004
251 + 31534753 = 31535004
313 + 31534691 = 31535004
353 + 31534651 = 31535004

Showing the first eight; more decompositions exist.
