Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489334, here are decompositions:

157 + 31489177 = 31489334
271 + 31489063 = 31489334
307 + 31489027 = 31489334
601 + 31488733 = 31489334
787 + 31488547 = 31489334
853 + 31488481 = 31489334
1063 + 31488271 = 31489334
1123 + 31488211 = 31489334

Showing the first eight; more decompositions exist.
