Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567132, here are decompositions:

41 + 31567091 = 31567132
83 + 31567049 = 31567132
89 + 31567043 = 31567132
269 + 31566863 = 31567132
293 + 31566839 = 31567132
383 + 31566749 = 31567132
419 + 31566713 = 31567132
521 + 31566611 = 31567132

Showing the first eight; more decompositions exist.
