Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574598, here are decompositions:

67 + 31574531 = 31574598
101 + 31574497 = 31574598
109 + 31574489 = 31574598
131 + 31574467 = 31574598
149 + 31574449 = 31574598
179 + 31574419 = 31574598
229 + 31574369 = 31574598
269 + 31574329 = 31574598

Showing the first eight; more decompositions exist.
