Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522684, here are decompositions:

71 + 31522613 = 31522684
101 + 31522583 = 31522684
131 + 31522553 = 31522684
191 + 31522493 = 31522684
233 + 31522451 = 31522684
251 + 31522433 = 31522684
311 + 31522373 = 31522684
353 + 31522331 = 31522684

Showing the first eight; more decompositions exist.
