Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576274, here are decompositions:

7 + 31576267 = 31576274
13 + 31576261 = 31576274
43 + 31576231 = 31576274
73 + 31576201 = 31576274
157 + 31576117 = 31576274
271 + 31576003 = 31576274
283 + 31575991 = 31576274
337 + 31575937 = 31576274

Showing the first eight; more decompositions exist.
