Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489542, here are decompositions:

23 + 31489519 = 31489542
53 + 31489489 = 31489542
79 + 31489463 = 31489542
109 + 31489433 = 31489542
131 + 31489411 = 31489542
151 + 31489391 = 31489542
179 + 31489363 = 31489542
193 + 31489349 = 31489542

Showing the first eight; more decompositions exist.
