Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535488, here are decompositions:

59 + 31535429 = 31535488
71 + 31535417 = 31535488
107 + 31535381 = 31535488
167 + 31535321 = 31535488
269 + 31535219 = 31535488
317 + 31535171 = 31535488
431 + 31535057 = 31535488
617 + 31534871 = 31535488

Showing the first eight; more decompositions exist.
