Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535098, here are decompositions:

17 + 31535081 = 31535098
41 + 31535057 = 31535098
137 + 31534961 = 31535098
227 + 31534871 = 31535098
311 + 31534787 = 31535098
347 + 31534751 = 31535098
359 + 31534739 = 31535098
389 + 31534709 = 31535098

Showing the first eight; more decompositions exist.
