Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535248, here are decompositions:

29 + 31535219 = 31535248
167 + 31535081 = 31535248
191 + 31535057 = 31535248
449 + 31534799 = 31535248
461 + 31534787 = 31535248
491 + 31534757 = 31535248
509 + 31534739 = 31535248
557 + 31534691 = 31535248

Showing the first eight; more decompositions exist.
