Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472602, here are decompositions:

11 + 31472591 = 31472602
101 + 31472501 = 31472602
113 + 31472489 = 31472602
251 + 31472351 = 31472602
263 + 31472339 = 31472602
311 + 31472291 = 31472602
401 + 31472201 = 31472602
419 + 31472183 = 31472602

Showing the first eight; more decompositions exist.
