Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472300, here are decompositions:

7 + 31472293 = 31472300
61 + 31472239 = 31472300
109 + 31472191 = 31472300
151 + 31472149 = 31472300
157 + 31472143 = 31472300
193 + 31472107 = 31472300
271 + 31472029 = 31472300
367 + 31471933 = 31472300

Showing the first eight; more decompositions exist.
