Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540444, here are decompositions:

3 + 31540441 = 31540444
101 + 31540343 = 31540444
227 + 31540217 = 31540444
233 + 31540211 = 31540444
263 + 31540181 = 31540444
281 + 31540163 = 31540444
431 + 31540013 = 31540444
587 + 31539857 = 31540444

Showing the first eight; more decompositions exist.
