Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472236, here are decompositions:

53 + 31472183 = 31472236
83 + 31472153 = 31472236
113 + 31472123 = 31472236
167 + 31472069 = 31472236
233 + 31472003 = 31472236
269 + 31471967 = 31472236
353 + 31471883 = 31472236
449 + 31471787 = 31472236

Showing the first eight; more decompositions exist.
