Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489592, here are decompositions:

73 + 31489519 = 31489592
103 + 31489489 = 31489592
181 + 31489411 = 31489592
193 + 31489399 = 31489592
229 + 31489363 = 31489592
313 + 31489279 = 31489592
349 + 31489243 = 31489592
523 + 31489069 = 31489592

Showing the first eight; more decompositions exist.
