Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522714, here are decompositions:

101 + 31522613 = 31522714
131 + 31522583 = 31522714
173 + 31522541 = 31522714
191 + 31522523 = 31522714
263 + 31522451 = 31522714
281 + 31522433 = 31522714
383 + 31522331 = 31522714
401 + 31522313 = 31522714

Showing the first eight; more decompositions exist.
