Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574232, here are decompositions:

29 + 31574203 = 31574232
31 + 31574201 = 31574232
59 + 31574173 = 31574232
101 + 31574131 = 31574232
139 + 31574093 = 31574232
191 + 31574041 = 31574232
211 + 31574021 = 31574232
233 + 31573999 = 31574232

Showing the first eight; more decompositions exist.
