Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472508, here are decompositions:

7 + 31472501 = 31472508
19 + 31472489 = 31472508
29 + 31472479 = 31472508
59 + 31472449 = 31472508
71 + 31472437 = 31472508
149 + 31472359 = 31472508
157 + 31472351 = 31472508
269 + 31472239 = 31472508

Showing the first eight; more decompositions exist.
