Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535548, here are decompositions:

131 + 31535417 = 31535548
137 + 31535411 = 31535548
167 + 31535381 = 31535548
227 + 31535321 = 31535548
467 + 31535081 = 31535548
491 + 31535057 = 31535548
587 + 31534961 = 31535548
677 + 31534871 = 31535548

Showing the first eight; more decompositions exist.
