Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523632, here are decompositions:

53 + 31523579 = 31523632
191 + 31523441 = 31523632
233 + 31523399 = 31523632
251 + 31523381 = 31523632
353 + 31523279 = 31523632
389 + 31523243 = 31523632
401 + 31523231 = 31523632
431 + 31523201 = 31523632

Showing the first eight; more decompositions exist.
