Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472702, here are decompositions:

3 + 31472699 = 31472702
223 + 31472479 = 31472702
409 + 31472293 = 31472702
463 + 31472239 = 31472702
523 + 31472179 = 31472702
571 + 31472131 = 31472702
661 + 31472041 = 31472702
673 + 31472029 = 31472702

Showing the first eight; more decompositions exist.
