Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602562, here are decompositions:

23 + 31602539 = 31602562
41 + 31602521 = 31602562
239 + 31602323 = 31602562
281 + 31602281 = 31602562
311 + 31602251 = 31602562
389 + 31602173 = 31602562
419 + 31602143 = 31602562
491 + 31602071 = 31602562

Showing the first eight; more decompositions exist.
