Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489452, here are decompositions:

19 + 31489433 = 31489452
41 + 31489411 = 31489452
53 + 31489399 = 31489452
61 + 31489391 = 31489452
89 + 31489363 = 31489452
103 + 31489349 = 31489452
173 + 31489279 = 31489452
193 + 31489259 = 31489452

Showing the first eight; more decompositions exist.
