Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489604, here are decompositions:

193 + 31489411 = 31489604
241 + 31489363 = 31489604
457 + 31489147 = 31489604
541 + 31489063 = 31489604
577 + 31489027 = 31489604
613 + 31488991 = 31489604
673 + 31488931 = 31489604
1123 + 31488481 = 31489604

Showing the first eight; more decompositions exist.
