Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560132, here are decompositions:

53 + 31560079 = 31560132
59 + 31560073 = 31560132
73 + 31560059 = 31560132
103 + 31560029 = 31560132
113 + 31560019 = 31560132
151 + 31559981 = 31560132
181 + 31559951 = 31560132
271 + 31559861 = 31560132

Showing the first eight; more decompositions exist.
