Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470098, here are decompositions:

31 + 31470067 = 31470098
61 + 31470037 = 31470098
109 + 31469989 = 31470098
241 + 31469857 = 31470098
337 + 31469761 = 31470098
367 + 31469731 = 31470098
409 + 31469689 = 31470098
571 + 31469527 = 31470098

Showing the first eight; more decompositions exist.
