Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535792, here are decompositions:

199 + 31535593 = 31535792
241 + 31535551 = 31535792
373 + 31535419 = 31535792
619 + 31535173 = 31535792
661 + 31535131 = 31535792
709 + 31535083 = 31535792
733 + 31535059 = 31535792
811 + 31534981 = 31535792

Showing the first eight; more decompositions exist.
