Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502444, here are decompositions:

3 + 31502441 = 31502444
13 + 31502431 = 31502444
73 + 31502371 = 31502444
157 + 31502287 = 31502444
283 + 31502161 = 31502444
313 + 31502131 = 31502444
331 + 31502113 = 31502444
487 + 31501957 = 31502444

Showing the first eight; more decompositions exist.
