Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535132, here are decompositions:

19 + 31535113 = 31535132
73 + 31535059 = 31535132
151 + 31534981 = 31535132
313 + 31534819 = 31535132
331 + 31534801 = 31535132
379 + 31534753 = 31535132
463 + 31534669 = 31535132
571 + 31534561 = 31535132

Showing the first eight; more decompositions exist.
