Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552992, here are decompositions:

73 + 31552919 = 31552992
101 + 31552891 = 31552992
109 + 31552883 = 31552992
113 + 31552879 = 31552992
139 + 31552853 = 31552992
271 + 31552721 = 31552992
283 + 31552709 = 31552992
311 + 31552681 = 31552992

Showing the first eight; more decompositions exist.
