Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601252, here are decompositions:

61 + 31601191 = 31601252
73 + 31601179 = 31601252
211 + 31601041 = 31601252
229 + 31601023 = 31601252
283 + 31600969 = 31601252
409 + 31600843 = 31601252
499 + 31600753 = 31601252
811 + 31600441 = 31601252

Showing the first eight; more decompositions exist.
