Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539642, here are decompositions:

59 + 31539583 = 31539642
73 + 31539569 = 31539642
229 + 31539413 = 31539642
241 + 31539401 = 31539642
293 + 31539349 = 31539642
311 + 31539331 = 31539642
313 + 31539329 = 31539642
353 + 31539289 = 31539642

Showing the first eight; more decompositions exist.
