Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535144, here are decompositions:

13 + 31535131 = 31535144
31 + 31535113 = 31535144
37 + 31535107 = 31535144
61 + 31535083 = 31535144
163 + 31534981 = 31535144
271 + 31534873 = 31535144
313 + 31534831 = 31535144
547 + 31534597 = 31535144

Showing the first eight; more decompositions exist.
