Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582862, here are decompositions:

43 + 31582819 = 31582862
229 + 31582633 = 31582862
331 + 31582531 = 31582862
349 + 31582513 = 31582862
373 + 31582489 = 31582862
463 + 31582399 = 31582862
541 + 31582321 = 31582862
613 + 31582249 = 31582862

Showing the first eight; more decompositions exist.
