Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472724, here are decompositions:

61 + 31472663 = 31472724
113 + 31472611 = 31472724
137 + 31472587 = 31472724
223 + 31472501 = 31472724
373 + 31472351 = 31472724
431 + 31472293 = 31472724
433 + 31472291 = 31472724
463 + 31472261 = 31472724

Showing the first eight; more decompositions exist.
