Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480264, here are decompositions:

5 + 31480259 = 31480264
173 + 31480091 = 31480264
317 + 31479947 = 31480264
383 + 31479881 = 31480264
443 + 31479821 = 31480264
461 + 31479803 = 31480264
521 + 31479743 = 31480264
593 + 31479671 = 31480264

Showing the first eight; more decompositions exist.
