Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535482, here are decompositions:

53 + 31535429 = 31535482
59 + 31535423 = 31535482
71 + 31535411 = 31535482
101 + 31535381 = 31535482
263 + 31535219 = 31535482
269 + 31535213 = 31535482
311 + 31535171 = 31535482
359 + 31535123 = 31535482

Showing the first eight; more decompositions exist.
