Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552804, here are decompositions:

71 + 31552733 = 31552804
83 + 31552721 = 31552804
251 + 31552553 = 31552804
317 + 31552487 = 31552804
383 + 31552421 = 31552804
401 + 31552403 = 31552804
593 + 31552211 = 31552804
677 + 31552127 = 31552804

Showing the first eight; more decompositions exist.
