Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574434, here are decompositions:

5 + 31574429 = 31574434
71 + 31574363 = 31574434
107 + 31574327 = 31574434
131 + 31574303 = 31574434
137 + 31574297 = 31574434
173 + 31574261 = 31574434
233 + 31574201 = 31574434
467 + 31573967 = 31574434

Showing the first eight; more decompositions exist.
