Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522862, here are decompositions:

193 + 31522669 = 31522862
199 + 31522663 = 31522862
229 + 31522633 = 31522862
271 + 31522591 = 31522862
313 + 31522549 = 31522862
421 + 31522441 = 31522862
499 + 31522363 = 31522862
523 + 31522339 = 31522862

Showing the first eight; more decompositions exist.
