Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472598, here are decompositions:

7 + 31472591 = 31472598
11 + 31472587 = 31472598
61 + 31472537 = 31472598
97 + 31472501 = 31472598
109 + 31472489 = 31472598
149 + 31472449 = 31472598
239 + 31472359 = 31472598
307 + 31472291 = 31472598

Showing the first eight; more decompositions exist.
