Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472648, here are decompositions:

37 + 31472611 = 31472648
61 + 31472587 = 31472648
199 + 31472449 = 31472648
211 + 31472437 = 31472648
409 + 31472239 = 31472648
439 + 31472209 = 31472648
457 + 31472191 = 31472648
499 + 31472149 = 31472648

Showing the first eight; more decompositions exist.
