Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576702, here are decompositions:

29 + 31576673 = 31576702
83 + 31576619 = 31576702
173 + 31576529 = 31576702
191 + 31576511 = 31576702
263 + 31576439 = 31576702
293 + 31576409 = 31576702
419 + 31576283 = 31576702
449 + 31576253 = 31576702

Showing the first eight; more decompositions exist.
