Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472692, here are decompositions:

23 + 31472669 = 31472692
29 + 31472663 = 31472692
59 + 31472633 = 31472692
101 + 31472591 = 31472692
191 + 31472501 = 31472692
353 + 31472339 = 31472692
401 + 31472291 = 31472692
431 + 31472261 = 31472692

Showing the first eight; more decompositions exist.
