Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542302, here are decompositions:

73 + 31542229 = 31542302
139 + 31542163 = 31542302
199 + 31542103 = 31542302
271 + 31542031 = 31542302
313 + 31541989 = 31542302
331 + 31541971 = 31542302
409 + 31541893 = 31542302
433 + 31541869 = 31542302

Showing the first eight; more decompositions exist.
