Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522658, here are decompositions:

61 + 31522597 = 31522658
67 + 31522591 = 31522658
109 + 31522549 = 31522658
199 + 31522459 = 31522658
331 + 31522327 = 31522658
439 + 31522219 = 31522658
829 + 31521829 = 31522658
919 + 31521739 = 31522658

Showing the first eight; more decompositions exist.
