Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472714, here are decompositions:

103 + 31472611 = 31472714
127 + 31472587 = 31472714
277 + 31472437 = 31472714
421 + 31472293 = 31472714
523 + 31472191 = 31472714
547 + 31472167 = 31472714
571 + 31472143 = 31472714
607 + 31472107 = 31472714

Showing the first eight; more decompositions exist.
