Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552154, here are decompositions:

97 + 31552057 = 31552154
157 + 31551997 = 31552154
373 + 31551781 = 31552154
397 + 31551757 = 31552154
421 + 31551733 = 31552154
433 + 31551721 = 31552154
541 + 31551613 = 31552154
577 + 31551577 = 31552154

Showing the first eight; more decompositions exist.
