Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495098, here are decompositions:

79 + 31495019 = 31495098
149 + 31494949 = 31495098
179 + 31494919 = 31495098
191 + 31494907 = 31495098
211 + 31494887 = 31495098
281 + 31494817 = 31495098
317 + 31494781 = 31495098
331 + 31494767 = 31495098

Showing the first eight; more decompositions exist.
