Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485532, here are decompositions:

59 + 31485473 = 31485532
83 + 31485449 = 31485532
101 + 31485431 = 31485532
131 + 31485401 = 31485532
149 + 31485383 = 31485532
173 + 31485359 = 31485532
179 + 31485353 = 31485532
191 + 31485341 = 31485532

Showing the first eight; more decompositions exist.
